Real and imaginary parts of dielectric constant vs refractive index?

WebNov 26, 2024 · This polarisation is easily changed by applying an electric field parallel to the z -axis, but a field applied to the x-y plane has little effect on the polarisation. Consequently the dielectric permittivity is anisotropic. The refractive index, n, is given by the square root of the relative dielectric permittivity, i.e. √E. WebThe imaginary part of the index of refraction, i.e. $\kappa$, quantifies the dissipation of light through a medium. However, if one wants to quantify the dissipation due to nonretarded electric fields alone, the quantity that quantifies this is not $\epsilon_b$ but $\operatorname{Im}\frac{1}{\epsilon}$, where $\epsilon$ is the total dielectric ... pros of meditation
