Abstract
An exact radiometric model is proposed for the nonparaxial propagation of fully or partially coherent electromagnetic radiation within anisotropic and/or chiral media in terms of rectilinear ray propagation. The definition of the generalized radiance is motivated by a geometric interpretation, based on the plane-wave decomposition of the field in the medium. The new representations are illustrated through two examples, corresponding to the propagation of two-dimensional fields within birefringent and chiral media.
