Description
Summary:The scattering from a thin rectangular plate of a perfect conductor illuminated by an electromagnetic plane wave at glancing incidence is studied using a formula derived by the method of the Kobayashi potential, which is a form of Weber?Schafheitlin discontinuous integrals. Numerical results for the current density distribution and far-field pattern are presented. A part of these results are compared with those obtained from the approximation expression, which is derived from the current density induced on the half-plane. The agreement is relatively good, particularly for a large plate. The backscattering cross sections (radar cross sections) are obtained as a function of the dimension of the plate for various values of incident angles; our results agree well with the experimental data measured by Ross and others. Numerical results of the total scattering cross sections are also presented.
