THE SCATTERING OF ELECTROMAGNETIC WAVES BY PERFECTLY REFLECTING OBJECTS OF COMPLEX SHAPES.
Abstract
The objective of the contract was to carry out a theoretical investigation of the scattering of an incident plane electromagnetic wave by perfectly conducting bodies of somewhat irregular shape. The results were to be applicable in the so-called resonance region, where the major dimensions and of the order of a free-space wavelength in size. The objects which were investigated included a cone of finite height, a circular cylinder of finite length, a cube, a finned circular cylinder of infinite length, a finned sphere, and a hemisphere. Solutions and numerical results for the radar cross section were obtained for the finite cone, the finned cylinder, and the finned sphere. The solution for the hemisphere has been obtained and numerical results are in the process of being secured. Some attention also was given to the problem of altering the scattering characteristics of reflecting objects without altering their essential configurations. Results were obtained for scattering by a long wire. (Author)
