- Supplemental Material are files either to aid the reviewer or for publication alongside the manuscript. Appropriate items for publication as supplemental materials include data tables and text (e.g., appendixes) that are too lengthy or of too limited interest for inclusion in the article. A URL link will be included in the published article to allow users to navigate directly to the associated files. Note that subdirectories (folders) are not acceptable. Please name files appropriately, so that all files can reside at the root directory, allowing successful linking between the published paper and its associated supplemental material.
- All supplemental material for publication must be approved by the Journal Editor as part of a manuscript's normal review cycle, and must be listed in the reference section as follows:
"See supplemental material at [URL will be inserted by AIP] for [give brief description of material]."

- Multimedia files may be included in the online version of published papers. Multimedia consists of video, audio, and 3D rendering files. Readers can view these multimedia files by simply clicking on a link in the paper, provided the reader has a video player, such as Windows Media PlayerTM, QuickTime PlayerTM, or RealOne PlayerTM, installed. In addition to the multimedia file, please upload a static figure to represent the multimedia file in the article. The static file and the multimedia file should be numbered the same. Please add "(enhanced online)" after the figure citation in text and in the figure caption. There will be a link placed in the caption to bring the reader directly to the multimedia file.
- Video: Acceptable file formats include QuickTime nonstreaming video (.qt or .mov), MPEG (.mpg), and DV (.dv). The preferred formats are .mov and .mpg. Details about each of these file formats are outlined below. Note that AVI is no longer a recommended file format, because the wide variety of AVI codecs cannot be reliably archived. Please insert a representative “still” image, taken from the video, in the manuscript as a figure. Care should be taken to extract an image that has reasonable clarity of fine lines and details. Acceptable file formats for still images are JPEG (.jpg) and GIF (.gif).
- Audio: Acceptable file formats include PCM (.pcm), WAV (.wav), AIFF (.aif), and MP3 (.mp3) at 128 KB or greater.
Please follow these guidelines when preparing multimedia files for submission:
- When including multimedia, write the paper so that the print version, which does not contain multimedia functionality, can be understood on its own.
- Submit all multimedia source files initially with the manuscript.
- Treat all multimedia files as figures, numbered in sequence as they are referred to in text. (Multimedia files should not have a numbering scheme separate from the figures.)
- Please be sure to cite all multimedia files in the text, referred to by their figure number.
- For each multimedia file, provide a figure that is a static representation of the multimedia file. Also provide an accompanying caption. At the end of the caption, include the phrase "(enhanced online)." The multimedia file will be linked to the static image online.
- Video and other enhanced files should be in a format that can be viewed without difficulty. See the acceptable file formats section for specific submission requirements.
- Use of copyrighted material is not permitted.
- Use media players to check file properties and image/sound quality prior to submission. For video submissions, fonts, lines, and image details should be of sufficient size and weight to be visible when played at half size.
- It is important to pay attention to the file size to make download time reasonable because streaming formats are not acceptable for submission at this time. A recommended target size for each multimedia file is 3ndash;5 MB.
- Please use one of the accepted compression codecs to minimize file sizes.
- Animations must be formatted into a standard video file.
Please include information about your multimedia files. A caption or description of the content of the media file is required (similar to a typical figure caption). Additional metadata is also requested, but optional.
- Caption/description: Textual caption/description of the content of media object is required.
- Type: The nature or genre of the content of the media, such as video or audio, is desirable (optional).
- Format: This describes the media file type, such as QuickTime, DV, MPEG, PCM, or WAV (optional).
- Duration: This is the playing time of the media object, in units of seconds. It is applicable to video or audio media (optional).
- Frame size: For video only (not still images), the size of the video image, expressed as height × width in pixels, may be included (optional).
- Producer: Information about the software used to create the media object. Please include the name and version of the software (e.g., Adobe Premiere Elements v. 2.0) (optional).
