This relaxation is often described in terms of permittivity as a function of frequency, which can, for ideal systems, be described by the Debye equation. See more In electromagnetism, a dielectric (or dielectric medium) is an electrical insulator that can be polarised by an applied electric field. When a dielectric material is placed in an electric field, electric charges do not flow through the … See more The electric susceptibility χe of a dielectric material is a measure of how easily it polarises in response to an electric field. This, in turn, determines the electric permittivity of … See more In physics, dielectric dispersion is the dependence of the permittivity of a dielectric material on the frequency of an applied electric field. Because there is a lag between changes in polarisation and changes in the electric field, the permittivity of the … See more Paraelectricity is the nominal behaviour of dielectrics when the dielectric permittivity tensor is proportional to the unit matrix, i.e., an applied electric field causes polarisation and/or … See more Although the term insulator implies low electrical conduction, dielectric typically means materials with a high polarisability.
