Direct and Related Far-Field Inverse Scattering Problems for Spherical Electromagnetic Waves in Chiral Media |
N. M. Berketis |
ABSTRACT |
This paper studies the direct and inverse scattering problem when the incident electromagnetic field is a time harmonic point - generated wave in a chiral media and the scatterer is a perfectly conducting sphere. The exact Green’s function and the electric far-field patterns of the scattering problem are constructed. For a small sphere, a closed-form approximation of the scattered wave field at the source of the incident spherical wave is obtained. Also treats the same inverse problem using far-field results via the leading order term in the low-frequency asymptotic expansion of the scattering cross-section. |
