Theoretical results regarding the propagation of intense light through a two-component medium are presented. The light-induced scattering from such a medium can compensate for the usual linear scattering under certain conditions, thus giving rise to the so-called self-transparency effect (suppression of the scattering). The theoretical model is based on the flux theory of light scattering. It is also shown that the equation obtained through flux theory can also be derived by using the wave equation when the medium is treated as a composite (effective) medium and when the dispersion and Kerr-type nonlinear terms for such a composite medium are neglected. The complete equation without neglecting these two terms is solved numerically in order to study the effect of nonlinear scattering on soliton propagation. The problem of two oppositely traveling waves in such a composite medium without dispersion and Kerr-type terms is also discussed.
