Abstract :
A method of moments solution is presented for the problem of determining the electromagnetic aperture fields that occur when a circular cylindrical waveguide radiates into an anisotropic dielectric-covered ground plane. The method of moments solution is derived by using a reaction matching technique and by using K-space theory to develop the aperture matrix elements of the system. An example of radiation into an anisotropic dielectric is given. The anisotropic dielectric for this example is assumed to be formed by the presence of a static magnetic field placed within a plasma.<>
