Abstract
We consider the diffraction problem of a plane electromagnetic wave incident from a free space quadrant onto an anisotropic ferrite quadrant, in the presence of a perfectly conducting plane. An exact closed-form solution is obtained by means of the Wiener-Hopf technique. Asymptotic expressions are obtained for the far fields, and the existence of "shadow boundaries" in both quadrants is noted. For a certain range of the ferrite parameters, the configuration exhibits "intrinsic loss" at the corner where the three media meet. This known phenomenon is analyzed exactly here for the first time.
