Abstract
Ten dispersion relations due to dielectric fluctuations are derived for electromagnetic radiation whose two-point correlation is written as a product of two functions, one in space and the other in time. The time part is assumed to be a Markov process, and five different spatial-correlation functions are considered. The dispersion relations derived are applied to calculate frequency and wave-number dispersions for the irradiance of a monochromatic beam that is used to excite selectively a host species in a solid.
