Inverse scattering from an orthotropic medium

AbstractWe consider the inverse scattering problem of determining the shape of an orthotropic homogeneous medium from a knowledge of the far field pattern corresponding to incident time harmonic plane waves. We solve the direct problem by potential theory, show the uniqueness of the inverse problem and then use a ‘simple’ method recently developed by Colton and Kirsch (1996) and Colton and Monk (1997) to solve the inverse problem. Numerical examples are given showing the practicality of our method for solving the inverse problem
