Radiative transfer in anisotropic, weakly inhomogeneous media with internal sources

The transport of radiation in anisotropic, weakly inhomogeneous and spatially dispersive media with internal sources is considered on the basis of the relevant geometric optics far-field as a function of position and frequency. The second rank radiation intensity tensor is obtained directly from the autocorrelation of the electric far-field in terms of a second rank emissivity tensor and accounts for coherent as well as incoherent emission, along with the effects of generalized Faraday rotation. The case of Cerenkov radiation is considered in detail. (C) 1997 American Institute of Physics.
