Abstract

We present a parabolic approximation that incorporates reflection. With this approximation, there is no need to solve the parabolic equation for a coupled pair of solutions consisting of the incident and reflected waves. Rather, this approximation uses a synthetic wave whose spectral components manifest the incident and reflected waves.
