Permittivity — A dielectric medium showing orientation of charged particles creating polarization effects. Such a medium can have a higher ratio of electric flux to charge (permittivity) than empty space In electromagnetism, absolute permittivity is the measure … Wikipedia
Electric susceptibility — The electric susceptibility χe of a dielectric material is a measure of how easily it polarizes in response to an electric field. This, in turn, determines the electric permittivity of the material and thus influences many other phenomena in that … Wikipedia
Electric displacement field — In physics, the electric displacement field, denoted as , is a vector field that appears in Maxwell s equations. It accounts for the effects of free charges within materials. D stands for displacement, as in the related concept of displacement… … Wikipedia
