AUTHOR GUIDELINES FOR WASPAA 2021 PROCEEDINGS MANUSCRIPTS

The guidelines given below, including complete descriptions of the fonts, spacing, and related information for producing your proceedings manuscripts, are critical to produce the WASPAA 2021 proceedings with a more uniform look and IEEE Xplore-compatible PDFs.

All manuscripts must be submitted electronically as PDF files. All manuscripts must be formatted for white US letter paper (8.5 $\times$ 11 inches). Please do not use A4-size papers. All printed material, including text, illustrations, and charts, must be kept within a print area of 7.0 inches (178 mm) wide by 8.9 inches (226 mm) high. Do not write or print anything outside the print area. The top margin must be 1 inch (25 mm), except for the title page, and the left margin must be 0.75 inch (19 mm). All text must be in a two-column format. Columns are to be 3.29 inches (83.5 mm) wide, with a 0.31 inch (8 mm) space between them. Text must be fully justified.

Accepted papers must pass IEEE PDF Express ${}^{\text{TM}}$ format verification prior to publication. Format verification details will be announced with paper acceptance notification.

You must submit a fully completed, signed IEEE copyright release form after your manuscript is selected for presentation on the workshop. We must have this form before your paper can be published in the proceedings. The copyright form is available as a Word file, a PDF file, and an HTML file at [ieeecopyright]. Copyright form submission details will be announced with paper acceptance notification.

You are allowed a total of 5 pages for your document. Up to 4 pages may contain technical content, figures, and references, while the 5th page may contain only references. This is the max-imum number of pages that will be accepted, including all figures, tables, and references. Any documents that exceed the 5-page limit will be rejected. Any documents with a 5th page containing anything other than references will be rejected.

The paper title (on the first page) should begin 0.98 inches (25 mm) from the top edge of the page, centered, completely capitalized, and in Times 14-point, boldface type. The authors’ name(s) and affiliation(s) appear below the title in capital and lower case letters. Papers with multiple authors and affiliations may require two or more lines for this information.

To achieve the best rendering both in the proceedings and from the CD-ROM, we strongly encourage you to use Times-Roman font. In addition, this will give the proceedings a more uniform look. Use a font that is no smaller than nine point type throughout the paper, including figure captions.

In nine point type font, capital letters are 2 mm high. If you use the smallest point size, there should be no more than 3.2 lines/cm (8 lines/inch) vertically. This is a minimum spacing; 2.75 lines/cm (7 lines/inch) will make the paper much more readable. Larger type sizes require correspondingly larger vertical spacing. Please do not double-space your paper. True-Type 1 fonts are preferred.

The first paragraph in each section should not be indented, but all the following paragraphs within the section should be indented as these paragraphs demonstrate.

Major headings, for example, “1. Introduction”, should appear in all capital letters, bold face if possible, centered in the column, with one blank line before, and one blank line after. Use a period (“.”) after the heading number, not a colon.

Please do not paginate your paper. Page numbers, session numbers, and conference identification will be inserted when the paper is included in the proceedings. In addition, please do not change and remove the header and footer.

Illustrations must appear within the designated margins. They may span the two columns. If possible, position illustrations at the top of columns, rather than in the middle or at the bottom. Caption and number every illustration. All halftone illustrations must be clear black and white prints. Colors may be used, but they should be selected so as to be readable when printed on a black-only printer.

Since there are many ways, often incompatible, of including images (e.g., with experimental results) in a LaTeX document, an example of how to do this is presented in Fig. 1.

Equations should be placed on separate lines and consecutively numbered with equation numbers in parentheses flush with the right margin, as illustrated in (1) that gives the homogeneous acoustic wave equation in Cartesian coordinates [eWilliams1999],

$$\Delta^{2}p(x,y,z,t)-\displaystyle\frac{1}{c^{2}}\frac{\partial^{2}p(x,y,z,t)}{\partial t^{2}}=0,$$

(1)

where $p(x,y,z,t)$ is an infinitesimal variation of acoustic pressure from its equilibrium value at position $(x,y,z)$ and time $t$, and where $c$ denotes the speed of sound.

Symbols in your equation should be defined before the equation appears or immediately following. Use (1), not Eq. (1) or equation (1), except at the beginning of a sentence: “Equation (1) is …”

Use footnotes sparingly (or not at all!) and place them at the bottom of the column on the page on which they are referenced. Use Times 9-point type, single-spaced. To help your readers, avoid using footnotes altogether and include necessary peripheral observations in the text (within parentheses, if you prefer, as in this sentence).

List and number all bibliographical references at the end of the paper. The references should be numbered in order of appearance in the document. When referring to them in the text, type the corresponding reference number in square brackets as shown at the end of this sentence [cJones2003], [aSmith2000]. For LaTeX users, the use of the BibTeX style file IEEEtran.bst is recommended, which is included in the LaTeX paper kit available from the workshop website [waspaa17web].

The preferred spelling of the word acknowledgment in America is without an “e” after the “g.” Try to avoid the stilted expression, “One of us (R. B. G.) thanks …” Instead, try “R.B.G. thanks …” Put sponsor acknowledgments in the unnumbered footnote on the first page.
