Abstract
It is known that the two eigen plane waves incident to the generalized soft-and-hard/DB (GSHDB) boundary are reflected as from the PEC or PMC boundary, i.e., with reflection coefficients or , for any angle of incidence. The present paper discusses a more general class of boundaries by requiring that the reflection coefficients and , corresponding to the two eigen plane waves, have opposite values, with independent of the angle of incidence. It turns out that, there are two possibilities, for the class of GSHDB boundaries, and for another class, extending that of the perfect electromagnetic conductor (PEMC) boundaries. Matched waves at, and plane-waves reflected from, boundaries of the latter class are studied in the paper.
