Paper Preparation Instructions

It is important that you follow these instructions for preparing your paper for the conference proceedings.

Important Format Change
Please note that paper format has changed from a two-column layout to a one-column layout.

Paper Style Formatting

Final copy should be styled according to the templates provided. Papers should be in a single-column format, in 10 pt Times Roman or Calibri font style. All text should be single-spaced. A double space may be used when beginning a new section or paragraph. Paper Title MUST be 24 point Times Roman or Calibri font style with initial capitalization only. Title should be in bold face.

Please use as many as possible of your word processing software's automatic features. Input your text continuously; in other words, only insert hard returns at ends of paragraphs or headings, subheadings, lists, etc. Do not use space bar to make indents (e.g., to indicate paragraphs or in lists). A tab or an indent command should be used for this purpose.

Submission of Electronic Version: Submit the electronic versions (Word and PDF) through the ION Abstract Management Portal (AMP). When creating the PDF file please make sure all the fonts (including the true fonts) are embedded. If you have any questions please contact Miriam Lewis at 703-366-2723 or by e-mail


Your paper should be organized in the manner specified on the templates and samples provided. 

For Letter Size Paper: 8.5" x 11" paper use margins: top = 1.0" inches, bottom = 1.0" inches, and 0.75" inches for left and right. 

For A4 paper, use the following margins: right & left margin = 0.59", top and bottom margins = 1.18", title and authors list centered at the beginning of the paper.

Begin your paper with a brief Biography followed by the Abstract and Introduction. Your paper should conclude with Acknowledgments and (or) References

Full justify your text. Use automatic hyphenation and check spelling. Digitize or paste down figures.

Paper Length: Papers submitted for peer review should not exceed 15 pages. There is no page limit for papers not undergoing the peer review process.

Use of Graphics and Photos

Incorporate tables and graphs in the body of the text, centered within the text. Figure captions should be centered and placed at the bottom of the figure.

Figure axis labels are often a source of confusion. Use words rather than symbols. For example, write “magnetization,” or “magnetization (M)” not just “M.” Put units in parentheses. Do not label axes only with units. In the example, write “Magnetization (A/m)” or “Magnetization (A .m1).” Do not label axes with a ratio of quantities and units. For example, write “Temperature (K),” not “Temperature/K.” Multipliers can be especially confusing. Write “Magnetization (kA/m)” or “Magnetization (103 A/m).” Figure labels should be legible, about 10-point type.

Use of Tables

Tables should be centered within the text. Table captions should be centered above the table. Avoid placing tables before their first mention in the text. When possible, use a table editor to create tables for your electronic version. Do not use spaces to align the columns of your table. Do Not use the "columns" feature to create tables.  Identify each table with a bold numeric reference and center it at the top of your table.


Do not insert page numbers to your paper.


Your paper must be in English.

Paper Title

Use 24 point Times Roman or Calibri font style with initial capitalization only. Title should be in bold.
