The parameters are calculated of an electromagnetic wave propagating in a dielectric medium, which is a multiphase mixture of isotropic and anisotropic components. The dispersion equation is studied which is derived allowing for spatial dispersion giving rise to an additional branch in solving the equation and, correspondingly, to two waves, namely, a real wave and a virtual wave. The results are given of calculating numerically the scattering indices and the phase and group velocities of the two waves. In the case the calculations are made in terms of the Bourret approximation, the real wave alone must be treated.

The Bourret approximation for a many-component medium, which is homogeneous and isotropic statistically under an exponential coordinate dependence of the permittivity correlation function, is used to calculate the mean Green tensor of the electromagnetic wave equation. The frequency dependence of the wave component amplitudes of the mean Green tensor is calculated numerically. The results of the calculations suggest that a stochastic resonance effect occurs in the frequency band determined by the structure of the medium.B n p~6 n u x e~~u EYPPe AJIX MHOTOKOMIIOHeHTHOfi CTaTRCTUYeCKII OnHOpOAHOfi II U30TPOIIHOfi ,4II3JIeKTpHYeCKOfi CpeAbI npII 3KCIIOHeHqIIaJrbHOfi KOOPAIIHaTHOfi 3aBIICAMOCTA KOppenFIUIIOHHOfi @YHKUAA AA3JIeKTpAYeCKOfi npOHIIUaeMOCTH BbIYHCJIeH CpeHHIIfi TCH3OP rpHHa 3JIeKTPOMaTHIITHOTO BOJIHOBOrO YpaBHeHHX. npOBeAeH YHCJIeHHbIg PaCYeT YaCTOTHOfi 3aBACHMOCTA aMIIJIHTyjI BOJIHOBblX COCTaBJIXlorUIIX CpenHerO TeH3Opa FpHHa, pe3yJIbTaTbl KOTOpOrO n03BOJIXIOT rOBOPHTb 0 npORBJIeHIIII 3@@eKTa CTOXaCTAYeCKOrO pe30HaHCa B IIOJIOCe YBCTOT, OIIPeneJIFIeMOg CTpyKTypO8 Cpenbl.
