WebbThe permittivity describes how an electric field is affected within a medium. The E-field tends to polarize the molecules within the material, which make up a net electric field that opposes the applied E-field. As a result, the total E-field is less than it … Webb21 mars 2024 · Here we consider only the physical (real-valued) permittivity, which is the real part of the complex permittivity (typically indicated as ϵ ′ or ϵ r ′) for materials exhibiting significant loss. Permittivity varies significantly as a function of frequency. The values below are representative of frequencies from a few kHz to about 1 GHz.
