In analogy to magnetic susceptibility, electric susceptibility only occurs above.
2.
Where ? 0 is the electric constant, and ? is the electric susceptibility of the medium.
3.
The relative permittivity of a medium is related to its electric susceptibility,, as 1 + ? e } }.
4.
Permittivity is directly related to electric susceptibility, which is a measure of how easily a dielectric polarizes in response to an electric field.
5.
A more general version of this model ( which allows the polarization to vary with position ) is the customary approach using electric susceptibility or electrical permittivity.
6.
The "'electric susceptibility " "'? e " of a dielectric material is a measure of how easily it polarizes in response to an electric field.
7.
Where one is in the instantaneously comoving inertial frame of the material, ? is its electrical conductivity, ? e is its electric susceptibility, and ? m is its magnetic susceptibility.
8.
In addition to anisotropy in the electric polarizability ( electric susceptibility ), anisotropy in the magnetic polarizability ( " ?" 0, so this is not a source of optical birefringence in practice.
9.
Electric susceptibility is defined as the constant of proportionality ( which may be a tensor ) relating an electric field "'E "'to the induced dielectric polarization density "'P "'such that:
10.
Because of the Kramers Kronig relations, the wavelength dependence of the real part of the refractive index is related to the material susceptibility " ? " that appears in the Kramers Kronig relations is the electric susceptibility " ? " e = " n " 2 " 1.
