A second vital bit of information is the wavelength at the frequency of interest. This is easy enough to calculate for air (free space), but is reduced in higher dielectric matter. Both of these numbers can be obtained from another calculator in the toolbox. The information that you need is the frequency and the dielectric of the medium or material.

We hope that these tools are helpful in guiding you in the selection of the correct absorber for your application. If there are any questions please do not hesitate to fill out the request for information form and submit on line. Thank you.
