The inverse scattering problem is well known and studied in the literature, especially with far-zone data, i.e., with scatterers in the radiation zone. This paper addresses the near- zone inverse scattering problem with an evanescent wave as the illuminating field. In details, we studied the linearized near-field scattering operator for mono-dimensional inhomogeneous media from multi-frequency data in a 2D configuration. Using estab-lished mathematical results, the eigenspectrum of the operator is derived in closed form.

Abstract
The inverse scattering problem is well known and studied in the literature, especially with far-zone data, i.e., with scatterers in the radiation zone. This paper addresses the near- zone inverse scattering problem with an evanescent wave as the illuminating field. In details, we studied the linearized near-field scattering operator for mono-dimensional inhomogeneous media from multi-frequency data in a 2D configuration. Using estab-lished mathematical results, the eigenspectrum of the operator is derived in closed form.File in questo prodotto:
