First and second moments of an optical wave propagating in an absorptive random medium.
By using the path-integral technique, the first and second moments of the propagator in an absorptive random medium are evaluated. The effects of random fluctuations of absorption are taken into account. In this evaluation, the imaginary part of the dielectric permittivity is supposed to fluctuate synchronously with the real part according to the Kramers-Kronig relations. Some physical insight is discussed.
