Περίληψη:
The scattering problem of a time-harmonic electromagnetic plane wave by
a dielectric ellipsoid with a perfectly conductive confocal ellipsoidal
core is considered. A method for solving an inverse electromagnetic
scattering problem for the layered ellipsoid using near-field data or
far-field data is presented. The size and the orientation of the layered
ellipsoid can be obtained, using a finite number of measurements of the
low-frequency approximation of the electric scattered field or the
electric far-field pattern. Corresponding results for the dielectric
ellipsoid and the perfectly conductive ellipsoid are presented
considering them as physically degenerate forms of the layered
ellipsoid. Moreover, results for the layered sphere and the layered
spheroid may be obtained, considering them as geometrically degenerate
forms of the layered ellipsoid. (C) 2019 Elsevier B.V. All rights
