Webpermittivity, er, of a material is generally speci-fied for convenience. It is also known as the dielectric constant of that material. Equation (2) is valid only in the frequency domain unless permittivity is independent of the frequency. Most of materials are dispersive, that is, their permittivity is frequency-depen-dent.
