Realization of the Generalized Soft-and-Hard Surface

摘要

Boundary conditions generalizing those of the soft-and-hard surface were recentlyintroduced as an example of an ideal boundary on which the complex Poynting vector cannot have a normal component. It was shown that under such conditions, a boundary surface can be used as a polarization transformer for a reflected plane wave. The question how to realize the generalized soft-and-hard surface is considered here. Various possibilities are discussed based on a medium interface, slab of an anisotropic medium and a configuration of antennas.
