INVERSE SCATTERING FOR ANISOTROPIC MIRROR-IMAGE SYMMETRICAL MEDIA

An inverse medium scattering problem for a homogeneous slab of anisotropic dispersive medium is presented. The inverse problem is to recover the dyadic susceptibility kernel from the dyadic reflection kernels for obliquely incident transient electromagnetic plane waves. A time domain technique, based on wave splitting and invariant imbedding, is used. Mirror images enter into the formalism in a natural way and are therefore discussed. This leads to a simplified problem for a class of mirror image symmetric media. This is solved numerically and the stability of the algorithm is tested using noisy data.
