Instructions to Authors
The journal welcomes, for publication, full papers and short notes, reporting significant new results of research, in all areas of physics except space physics. The applied fields covered are electronics, electrical engineering, instrumentation and applied mathematics. However, papers in applied mathematics with emphasis on only derivation and proofs and having no direct physical significance, will not be considered. Review articles are also published.
SUBMISSION OF MANUSCRIPT
Manuscripts for consideration should be submitted, in triplicate and in floppy form to Editor, Indian Journal of Pure & Applied Physics, National Institute of Science Communication, K.S. Krishnan Marg, New Delhi 110 012. They should neither have been already published nor be under consideration elsewhere.
Manuscripts should be in English and typewritten on only one side of good quality paper, in double space, with adequate margin on all four sides. One original and two carbon or photocopy, each complete in all respects including abstract, illustrations, appendixes, etc. are to be submitted.
Authors may consult recent issues of the Journal to familiarize themselves with the general style and practices adopted in regard to the various elements of a paper.
Manuscript should be presented in as concise a form as possible. Good attention should be given to spelling and grammar. In giving names of chemical compounds and structures, abbreviations of units of measurements, symbols and notations, the style and practices recommended by the IUPAP and IUPAC, should be followed.
Frequently repeating combinations of words, e.g. electric field gradient (EFG), junction field effect transistor (JFET), stimulated Raman emission (SRE), should be abbreviated subsequently, indicating the abbreviated form in parentheses, as shown, at the place of their first occurrence.
Pages should be numbered consecutively and arranged in the following order. Title, authors’ name with their institutional affiliations and abstract, along with relevant footnotes whenever necessary (on a separate sheet); introduction; experimental details /theory /method/analysis; results; discussion; conclusions(s); acknowledgement; references and appendixes. Tables, captions for figures (with legends) and appendixes should be typed on separate sheets and attached at the end of the manuscript.
The title should be neither too brief/general nor unnecessarily long. It should reflect the content of the paper so as to derive the maximum advantage in indexing. If a paper forms part of a general series, a specific subtitle, indicating the particular aspect of the work covered in the paper, should be provided.
A short running title for the paper, the broad PACS subject heading under which it should be classified in the contents page (authors may consult the January or July issue of the journal for this purpose), and the author’s name and address for correspondence, should also be provided on the title page.
The abstract, usually not exceeding 200 words, should indicate the scope and significant content of the paper, highlighting the principal findings and conclusions. It should be in such a form that abstracting periodicals can use it without modification.
Long and elaborate introduction should be avoided. It should be brief and state the exact scope of the study in relation to the present status of knowledge in the field. Literature review should be limited strictly to what is necessary to indicate the essential background and the justification for undertaking the study.
Materials, methods, apparatus, etc.
The sources of materials and their purity, methods of preparation, procedure for measurements and their accuracies, etc. should be clearly stated to enable any other worker to repeat the work if necessary. New methods, techniques, theories, etc. should be described in adequate detail; but if they are well known, a mere literature reference to them will do; differences from standard ones, improvements or innovations should, however, be clearly mentioned.
Only such primary data are essential for understanding the discussion and main conclusions emerging from the study should be included. All secondary data as are of interest to a specific category of readership should not be included in the paper. Such data should be retained by the authors for supply, on request, to any interested research workers. A footnote to this effect may be inserted at the relevant place in the paper.
The results must be presented in a coherent sequence in a unified logical structure, avoiding repetition or confusion. Limitations of the results should be clearly stated.
The same data should not be presented in both tabular and graphic forms. Only such tables and figures as are essential should be included. Simple linear plots that can easily be discussed in the text, should not be included. Infrared, ultraviolet, NMR and other spectra, DTA curves, etc. should be included only if they pertain to new compounds and/or are essential to the discussions; otherwise only significant numerical data should be given in the text or in a table.
Long rambling discussion should be avoided. The discussion should deal with the interpretation of results without repeating information already presented under results. It should relate new findings to the known and include logical deductions. A separate section on ‘conclusions’ can be given only when they are well established and of outstanding significance. Mere observation of qualitative trends of results should be distinguished from firm conclusions. Also, limitations, if any, to the conclusions should be clearly pointed out.
Special attention should be given to the mathematical portions of the paper. Equations must be well separated from the text and written clearly with good separation between the successive lines. The usual norms of breaking long mathematical expressions should be adhered to. Equations should be numbered consecutively in Arabic numerals with the number in parenthesis near the right hand margin. Superscripts and subscripts should be clearly indicated in pencil by V and A sign respectively. Capital and small letters, particularly of the same letter when both occur, as well as letters or symbols likely to be confused one for the other, should be clearly distinguished. Special characters (e.g. Greek, script, vector, tensor, etc.) required must be indicated by marginal notes. Letters and symbols which should appear in bold face must be clearly indicated. To simplify typesetting: (i) long and complicated mathematical expressions which are frequently repeated should be replaced with single letter/symbol, without clashing with the others used in the paper, (ii) the “exp” form of complex exponential functions should be used; and (iii) to simplify fractions, the solidus (/) is to be used and fractional exponents are to be used instead of root signs, e.g.
Write exp |-iwo (t1-t 2)/2| and not e-iwo (t 1-t 2 )/2
Tables should be numbered consecutively in Arabic numerals and should bear brief titles. Column headings should be brief. Units of measurement should be abbreviated and placed below the headings. Nil results should be indicated and distinguished clearly from absence of data. Inclusion of structural formulae inside the tables should be avoided as far as possible. Tables should be referred to in the text by numbers and not by terms like ‘above’, ‘below’, ‘preceding’ or ‘following’. Results should not be presented to a greater accuracy than that of the method employed.
The number of illustrations should be kept to the minimum. Wherever possible, e.g. a number of individual analogous figures referring to different variables, substances, molecules, etc, may be combined into one composite figure. All illustrations should be numbered consecutively in Arabic numerals. Captions and legends to the figures should be self-explanatory. Line drawings should be made with Indian ink on whit drawing paper/cellophane sheet/tracing cloth, and drawn to approximately twice the printed size.
The letterings should be uniform, preferably in stencil, so as to be not less than 1.5 mm after reduction width-wise to full page size (165 mm) or column size (0mm). The size of geometrical shapes (used to distinguish different graphs), dots, lines, etc, should be sufficiently large to permit the necessary reduction without loss of detail. In the case of photographs, prints must be on glossy paper and contrasty. If an illustration is taken from another publication, reference to the source should be given and prior permission secured. Illustrations should be referred to in the text by numbers and not by terms like ‘above’, ‘following’ etc.
Acknowledgements should not be exuberant and must be made only to real assistance rendered in connection with the work reported in the paper.
References cited should be limited to the absolute minimum (particularly in the case of short notes) based on their essential relevance. In the text, references to literature should be numbered consecutively, in the order of their first occurrence, and should be indicated by superscript. Arabic numbers at the relevant places; as far as possible the placement of references on numerals or other symbols should be avoided; in such cases the reference may be given in parenthesis in running text, e.g. “this yielded for n a value of 2.3 (Ref. 5)”. Full bibliographic details for all the references mentioned in the text should be listed in serial order at the end of the paper.
citing references to research papers, names and initials of authors should be
followed, in order, by the title of the periodical in the abbreviated form
(underlined), the volume number (two lines underneath), the year within circular
brackets and the page number [e.g. Chandra B P & Shrivastava
K K, J Phys & Chem
Solids, 39 (1978) 939]. For names of periodicals, the abbreviations
followed by the Physics Abstracts should be used. For periodicals not covered
by Physics Abstracts, the title abbreviations should be according to the
Bibliographic Guide for editors and Authors, 1974, published by the American
In references containing up to four authors, the names of all the authors with their respective initials should be given. The abbreviations et al., idem and ibid should be avoided. When there are more that four authors, only the names of the first three authors with their respective initials should be given, followed by the words ‘et al’.

authors, the title of the book (underlined), name of publisher and place of
publication within circular brackets and year and page(s0
[e.g. Clayton G B, Operational amplifiers (Newnes-Butterworths,
Proceedings of conferences and symposia should be treated in the same manner as books. References to a paper presented at a conference, the proceedings of which are not published, should include, in the following order, names and initials of authors, title of the paper (underlined), name of the conference, and where and when it was held (e.g. Herczeg P, Symmetry-violating kaon decays, paper presented to the International Conference on High Energy Physics and Nuclear Structure, Vancouver, Canada, 13-17 August 1979). Reference to a thesis should include the name of the author, title of the thesis (underlined), university or institutions to which it was submitted and year of submission (e.g. Mehrotra S N, Many-body techniques and their applications to interacting bosons, Ph D thesis, Ranchi University, 1976).

The International Patent Classification, which is commonly referred to as IPC: Int. Cl., is based on an international multi-lateral treaty administered by World Intellectual Property Organization, Geneva, Switzerland (WIPO; website: www.wipo.int). It is a hierarchical classification system, comprising sections, classes, subclasses and groups (main groups and subgroups), used to classify and retrieve patent documents (patent applications, specifications of granted patents, utility models, etc.). It also serves as an instrument for orderly arrangement of patent documents, a basis for selective dissemination of information and a basis for investigating the state of the art in given fields of technology. IPC is administered to provide a common system of classification accepted worldwide under Strasbourg Agreement (1975). It is regularly updated to include changes and advances in technology and commercial practices. New edition is published every five years. The current (seventh) edition (Int. Cl.7) has entered into force with effect from 1 January 2000 and is valid up to December 2005. The authentic version (English and French) of the 6th and 7th editions of the IPC are available on WIPO website, permitting the user to browse the text of the classification in order to find the relevant IPC symbol. The next, eighth, edition of the IPC will enter into force on January 1, 2006.
In order to cater the needs of IPC classification, the research journals brought out by NISCAIR have initiated to assign IPC codes to each article (wherever possible) for retrieval of information with the expectations that this will create more awareness and interests on these articles among the readers and will help NISCAIR to achieve its mandate of dissemination of science and technology information more emphatically.
The Classification is indispensable for the retrieval of patent documents in the search for “prior art”. Such retrieval is needed by patent-issuing authorities, potential inventors, research and development units, and others concerned with the application or development of technology.
The seventh edition of the IPC consists of 8 sections, designated by one of the capital letters ‘A’ through ‘H’, 120 classes, 628 subclasses and approximately 69,000 groups. The groups are either main groups or subgroups. Main group symbols consist of the subclass symbol followed by one- to three- digit numbers, the oblique stroke and the number 00, e.g., A01B1/00. Subgroups form subdivisions under the main groups. Each subgroup symbol includes the subclass symbol followed by the one- to three- digit numbers of its main group, the oblique stroke and a number of at least two digits other than 00, e.g., A01B1.02.
