The Scattering of Plane Electromagnetic Waves by a Perfectly Conducting Hemisphere or Hemispherical Shell
Abstract
The exact form of the diffraction pattern produced by electromagnetic waves falling upon a body of finite size is of interest in the calibration of radar equipment. At the present time, to the author's knowledge, the only finite object for which this pattern is known for all angles of incidence is the sphere. Solutions have been obtained for other finite bodies which are valid for certain directions and polarizations of the incident wave, as well as many approximations when the ratio of wavelength to physical dimensions is very large or very small. This investigation deals with the scattering by a hemispherical shell or solid hemisphere for a plane wave of arbitrary polarization and angle of incidence, where the ratio of wavelength to physical size is unrestricted. A formal solution is obtained for the general case, in the form of an infinite set of linear equations in the unknown field coefficients.
