Article structure

Subdivision - numbered sections

Divide your article into clearly defined and numbered sections. Subsections should be numbered:
1.1 (then 1.1.1, 1.1.2, ...), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to 'the text.' Any subsection may be given a brief heading. Each heading should appear on its separate line.

Introduction
State the objectives of the work and provide an adequate background, avoiding a detailed review of the literature or a summary of the results.

Material and methods
Provide sufficient details to allow the work to be reproduced by an independent researcher. Methods already published should be summarized and indicated by a reference. If quoting directly from a previously published way, use quotation marks and cite the source. Any modifications to existing methods should also be described.

Theory/calculation
The "Theory" section should lay the foundation for further work. But, on the contrary, the "Calculation" section is a practical development of the theoretical basis.

Results
Results should be clear and concise.

Discussion
There should explore the significance of the results of the work, not repeat them. A combined Results and Discussion section is often appropriate.

Conclusions
The study's main conclusions may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section.

Appendices
Formulae and equations in appendices should be given separate numbering: Eq. (A.1), etc. Similarly, for tables and figures: Table A.1; Fig. A.1, etc.

Essential title page information

• Title. Concise and informative. Avoid abbreviations and formulae where possible.

• Author names and affiliations. Please clearly indicate each author's given name(s) and family name(s) and check that all words are accurately spelled. Below the names, present the authors' affiliation addresses (where the actual work was done). Indicate all affiliations with a lowercase superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and, if available, the e-mail address of each author.
• Corresponding author. Indicate who will handle correspondence at all stages of refereeing and publication.

Abstract
A concise and factual abstract is required. The abstract should briefly state the research's purpose, principal results, and significant conclusions. An abstract must be able to stand alone. For this reason, References should be avoided, but if essential, cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if necessary, they must be defined at first mention in the abstract.

Keywords
Immediately after the abstract, provide a maximum of 10 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, 'and,' 'of'). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.

Acknowledgements
Collate acknowledgments in a separate section at the end of the article before the references. Please do not include them on the title page, as a footnote to the title, or otherwise. List here those
individuals who provided help during the research (e.g., providing language help, writing assistance, or proof reading the article, etc.).

Units
Follow internationally accepted rules and conventions: use the international system of units (SI). If other units are mentioned, please give their equivalent in SI.

Math formulae
Please submit math equations as editable text and not as images. Present simple formulae in line with standard text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. Number consecutively any equations that must be displayed separately from the text (if referred to explicitly in the text).

Tables
Please submit tables as editable text and not as images. Tables can be placed either next to the relevant text in the article or on separate pages (s) at the end. Number tables consecutively by their appearance in the text and place any table notes below the table body. Be sparing in using tables and ensure that the data presented in them do not duplicate results described elsewhere in the article. Please avoid using vertical rules and shading in table cells.

References
Citation in text
Please ensure that every reference cited in the text is also in the reference list (and vice versa). Any references cited in the abstract must be given in full. Unpublished results and personal communications are not recommended in the reference list but may be mentioned in the text. The citation of a reference as 'in press' implies that the item has been accepted for publication. The list of References must contain at least 30% of articles published over the past five years and no more than 20% self-citation. Cite References by number in AIP style (https://aip.scitation.org/php/authors/manuscript). References must not exceed 4×N, where N is the number of paper pages in an EEJP format. Numbering in the order of referring in the text, e.g., [1], [2-5], etc. References should be listed in numerical order of citation in the text at the end of the paper.
