Permittivity vs frequency
Webpermittivity (electric permittivity): Permittivity, also called electric permittivity, is a constant of proportionality that exists between electric displacement and electric field intensity. This constant is equal to approximately 8.85 x 10 -12 farad per meter (F/m) in free space (a vacuum). In other materials it can be much different, often ...
