A bistatic inverse scattering problem for electromagnetic waves

In this paper we discuss a bistatic inverse scattering problem for Maxwell's equations. We show that both the electric permittivity and magnetic permeability can be uniquely recovered from the knowledge of S(s, theta, theta') for all s is an element of R and special pairs of orthonormal vectors (theta,theta(')) provided that they are close to constants, where S(s, theta, theta(')) is the scattering kernel associated with Maxwell's equations. In other words, in this scattering experiment, measurements are made on a set of a priori arranged pairs of incoming and reflected directions. (C) 2000 American Institute of Physics.
