Abstract
A statistical description of the electromagnetic wave propagation in a two-component chiral composite is presented. We develop the strong-property-fluctuation theory which is a generalization of the strong-permittivity-fluctuation theory for nonhomogeneous chiral media. The Dyson equation for the exciting electromagnetic field is solved in the bilocal approximation. Wave propagation in the composite can be described in this manner by a nonlocal effective medium containing information about the spatial correlations of the material properties. For length scales larger than the correlation length, the system may be homogenized and we obtain a local effective medium theory.
