Dielectric Susceptibility


a quantity characterizing the capability of a dielectric to be polarized. Quantitatively dielectric susceptibility equals the proportionality coefficient K in the relationship P = kE, where E is the intensity of the electric field and P is the polarization of the dielectric (the dipole moment per unit volume of the dielectric). The dielectric properties of a substance are characterized by dielectric susceptibility, as well as by its dielectric constant ∊. The relationship between these two properties is ∊ = 1 + 4πk.
