Diffraction of an Hpolarized electromagnetic wave by a circular cylinder with an infinite axial slot
Abstract
Three methods of solution are provided for the problem of scattering and diffraction of a TE polarized plane wave by an infinite circular cylinder having an infinite axial slot. In one method of solution, the aperture field integral equation (AFIE) method, the fields in and around the cylinder are found from the aperture E field and the cylindrical Green's functions for the interior and exterior of a cylinder. In the other two methods the fields are determined from the surface current and solution of the H field integral equation (HFIE) or the E field integral equation (EFIE). The field in the aperture of the cylinder is found by the three methods and the advantages of each method of solution are discussed. In addition it is also shown that for shell thickness less than 1/20th of a wavelength, the aperture fields do not differ significantly from those of an infinitely thin shell cylinder.
