SCATTERING BY A SPHERICAL SHELL WITH A CIRCULAR APERTURE,
Abstract
A preliminary study of the scattering behavior of a spherical shell with a circular aperture is presented. The shell is assumed to be perfectly conducting and infinitesimally thin, and is illuminated by a plane electromagnetic wave symmetrically incident upon the aperture. Several different approaches to the solution of this problem are discussed, and the most promising one, the method of least square error, is described in detail. A numerical approach based on this scheme is devised, and values for the surface and back scattered far fields are given. In effect, the aperture and cavity provide a reactive load which modifies the scattering behavior of the complete shell (or sphere), and an example shows the cross section reduction achievable in this manner. Experimental confirmation was obtained, and the study is continuing. (Author)
