Permittivity - Wikipedia

Webpermittivity or dielelectric constant(ε). It describes the tendency of a material to polarize in response to an applied electrical field. It is a dimensionless parameter, defined as the ratio of the external (applied) field E0(the field without the dielectric) to the electric field inside the dielectric, E: ε= E0/ E WebPermittivity. Relative permittivity (εr) also known as the dielectric constant is a measure of the electric polarizability of a dielectric and is the ratio of the permittivity of a substance to the permittivity of space (Chisca et al., 2011).
