The complex permittivity is usually a complicated function of frequency ω, since it is a superimposed description of dispersion phenomena occurring at multiple frequencies. The dielectric function ε(ω) must have poles only for frequencies with positive imaginary parts, and therefore satisfies the … Zobacz więcej In electromagnetism, the absolute permittivity, often simply called permittivity and denoted by the Greek letter ε (epsilon), is a measure of the electric polarizability of a dielectric. A material with high permittivity … Zobacz więcej In electromagnetism, the electric displacement field D represents the distribution of electric charges in a given medium resulting from the presence of an electric field E. This distribution includes charge migration and electric dipole reorientation. … Zobacz więcej The linear permittivity of a homogeneous material is usually given relative to that of free space, as a relative permittivity εr (also called Zobacz więcej In general, a material cannot polarize instantaneously in response to an applied field, and so the more general formulation as a function of time is That is, the polarization is a convolution of the electric … Zobacz więcej The standard SI unit for permittivity is farad per meter (F/m or F·m ).
