SUBMISSION:
Manuscripts should be submitted to the Editorial Board by electronic mail (UJPO {at} ifo. lviv. ua). In case of any ambiguities in the text and equations or insufficient quality of figures and lettering, Editorial Board may require resubmitting necessary materials. Articles should be accompanied by the Warranty Form and the additional documents necessary for Ukrainian contributors, which may be sent by conventional mail or electronic mail (e.g., PDF file).

PREPARATION OF MANUSCRIPTS:
Manuscripts are to be written in English, using Microsoft® Word™97 (MS Office™97), or later versions (file formats DOC, DOCX, or RTF). The manuscript should be arranged in the following order: title of the article, authors names, institutions and addresses, abstract and keywords, text, Funding, acknowledgments, disclosures, appendices, and references. As a rule, articles should be divided into sections (Introduction, Experimental methods, Results and discussion, Conclusions, etc.).

Page layout and length
The text should be typed, using Times New Roman font (10-point size, 1.2-line spacing). Margins: Top – 3.0, bottom – 4.7, left – 3.5 and right – 3.5 cm, paper size – А4.

1. Title
Use the initial cap for the first word in the title or for proper nouns.
1.1. Author names.
Author names should appear as used for conventional publication, with surname followed by initials or first and middle names. Every effort should be made to keep author names consistent from one paper to the next as they appear within our publications.
1.2. Author affiliations.
If all authors share one affiliation, superscript numbers are not needed. For different affiliations, all authors must have superscripts to call out each affiliation. Hard returns (Enter key) must be used to separate each individual affiliation. Abbreviations should not be used. Please include the country at the end of the affiliation.

2. Abstracts.
Each manuscript requires a leading abstract (less than 100–150 words) in English summarising significant coverage and findings. If the work of another author is cited in the abstract, that citation should be written out without a number, (e.g., journal, volume, first page, and year in brackets [Ukr.J.Phys.Opt., 22: 1234 (2014)]), and a separate citation should be included in the body of the text.

3. Keywords Three to six keywords are required, which characterise the contents of the article.

4. Main text
Section headings may be numbered consecutively and consistently throughout the paper in Arabic numbers and typed in bold. Use an initial capital letter followed by lowercase, except for proper names, abbreviations, etc. Do not include references to the literature, illustrations, or tables in headings. Subsection headings may be numbered consecutively in Arabic numbers and typed in italic bold. Sub-subsection headings may be numbered consecutively in Arabic numbers and typed in italic. The text of the sub-subsection should follow the title.
Please note the references should appear at the end of the article after the Funding and Acknowledgments sections. The first reference cited in the main text must be [1].

5. Equations, figures, supplementary materials, and tables
5.1. Equations
All display equations should be created in MathType. Inline equations can be created with this tool or by using a keyboard and Unicode characters where needed for the best quality line spacing. We strongly encourage authors to use MathType 6.9.
The equations should be numbered with consecutive Arabic numbers. The configuration file for the MathType 6.9 can be downloaded (Formula.Preferences.UJPO.eqp).
5.2. Figures
Figures may be inserted immediately into the text. All of them should be numbered with consecutive Arabic numbers, have descriptive captions and be referred to in the text as e.g. Fig. 1. Captions should be set immediately below the figures. Figures should be prepared in a readable computer form, with the resolution not less than 450 dpi for grayscale or black/white figures (JPEG or PS formats). Colour figures should be prepared only in TIFF or JPEG format (not less than 300 dpi). The figure width should not exceed 14 cm. The line thickness must be chosen on this basis and all the lettering, and symbols should correspond to the text font size. Figures should never be placed in a table environment, embedded inside the text, or included within a list. All the figures should be centered. No part of a figure should go beyond the typing area. Place figures as closely as possible to where they are mentioned in the text. Figures should be numbered consecutively in the order of appearance and citation in the text. Be sure to cite every figure.
5.3. Tables
Insert tables into the text or gather them at the end of the article. Number tables consecutively with Arabic numbers and give each a clear descriptive caption at the top.
5.3.1. Supplementary materials. Supplementary materials (up to 10 MB), such as visualizations, Data Files, etc. can be uploaded after agreement with Editorial Group.

Funding. Authors may add the details about a funder that are required, or they may be added to the Acknowledgments. At the submissions, please include funder names and grant numbers in the manuscript.
Acknowledgments. Acknowledgments should be included at the end of the document. Additional information crediting individuals who contributed to the work being reported.
Disclosures. Disclosures should be listed in a separate section “Disclosures” at the end of the manuscript. If there are no disclosures, then list “The authors declare no conflicts of interest.”

6. References
The references should be prepared in the APA style. References should appear at the end of the article after the Funding and Acknowledgements sections as:

PRICING AND PAYMENT POLICY

1. Publication of articles in this journal is charged. Ukrainian Journal of Physical Optics is partially Open Access journal. The payment for their publication is determined by the budget of the journal and is calculated on the basis of a so-called ‘one author’s sheet’ (see the Ukrainian publishing-industry regulations on this subject). The APC in 2024 for one published "author sheet" for Ukrainian contributors equals 8677.32 UAH, while for contributors from abroad, it is 1200 Euro.

2. Payment for the publication of articles is contributed by the authors themselves, the institutions where the authors work, or their sponsors.

3. Members of the Editorial Board of the journal become free of payment for publication of their articles.

4. If any article is published in co-authorship with collaborators from the Institute, it is not paid for.

5. Publication of any article is free of charge if it is ordered by the Editorial Board itself.

6. The calculation of the cost of one published article, under the conditions when some categories of the authors are free of payment (see the item 3), is implemented according to the following scheme: FC = (GC/TA)×(TA – FA), where FC is the final cost of publication of the article, GC the general cost of publication of this article, TA the total number of co-authors of the article, and FA the number of free-of-charge co-authors mentioned in the item 3.

7. The journal's revenue sources are articles processing charges and subscriptions.
