Multipole Methods for Scattering From a Conducting Cylinder Over a Dielectric Half-Space

Two different but equivalent multipole methods are applied to the problem of determining the scattering of an electromagnetic wave by a perfectly conducting cylinder over a dielectric half-space. Numerical results are presented for different sets of parameter values. The results seem to be in good agreement with those obtained by geometrical optics methods for the high-frequency case, and qualitative results can be obtained by a relatively simple procedure based on geometrical optics.
