摘要：

Perfect electromagnetic conductor (PEMC) is a nonreciprocal generalization of both the perfect electric conductor (PEC) and the perfect magnetic conductor (PMC). Because PEMC does not allow electromagnetic energy to enter, it can serve as boundary material. Possibilities for the realization of a PEMC boundary are studied in terms of a layer of certain nonreciprocal materials resting on a PEC plane. It is shown that the parameters of a bi-isotropic or a gyrotropically anisotropic medium can be chosen so that the interface of the layer acts as a PEMC boundary to normally incident waves. After a modification of medium parameters, the same is shown to be asymptotically valid for arbitrary plane waves. A structure for the realization of such a boundary is suggested.
