Magnetic line source diffraction by a perfect electromagnetic conductor (PEMC) step.

In this paper, an analytic theory for the magnetic line source diffraction by a perfect electromagnetic conductor (PEMC) step is developed. Using the duality transformation, introduced by Lindell and Sihvola, transformations have been made from the diffraction of a magnetic line source by a perfect electric conductor (PEC) step. As an application, plane wave diffracted from a planar interface of air and PEMC media is studied. PEC and PMC are the limiting cases, while there is no cross-polarized component.
