Abstract

The electromagnetic inverse-scattering problem is solved by use of a local reflection model in inhomogeneous media. New renormalized perturbation solutions in explicit forms are obtained for reconstruction of dielectric profiles from the global reflection coefficient at the surface of the medium. A coordinate recovery transform is introduced for rigorous recovery of the geometric lengths from the stretched coordinates in the inversion procedure. Explicit solutions from the Green’s-function approach and the spectral theory are unified with the local reflection model. Numerical inversion is performed on band-limited reflection coefficients in the frequency domain.
