Abstract :
The perfect electromagnetic conductor (PEMC) is a generalization of both the perfect electric conductor (PEC) and the perfect magnetic conductor (PMC). As shown previously, the PEMC boundary can be realized using a gyrotropic layer backed by a PEC plane. If the axial permittivity and permeability are infinite and the other (lossless) parameters are chosen appropriately, the PEMC boundary condition can be satisfied exactly for a fixed frequency. In this paper, we continue the analysis of the PEMC boundary realization, taking into account the effect of finite axial parameters and also losses in the structure. Including these real-world deviations from the ideal case, we still get a useful PEMC approximation.
