In this work the scattering problem of a time-harmonic electromagnetic plane wave by a dielectric ellipsoid is considered. A low-frequency formulation of the direct scattering problem as well as Rayleigh expansions are described. By using far-field or near-field data the corresponding inverse scattering problem determining both the semiaxes and the orientation of the ellipsoid is solved completely. A finite number of measurements of the leading-order term of the electric far-field pattern or the electric scattered field in the low-frequency approximation can give the appropriate information. The orientation of the ellipsoid is specified by using the Euler angles. Corresponding results for spheroid. sphere. needle and disc are obtained considering them as geometrically degenerate forms of the ellipsoid for suitable values of the geometrical parameters. |
