Abstract: A new concept of a directional, non-reciprocal metasurface (MSF) where the polarization of the transmitted wave can be selected at will is presented. Each cell of the proposed MSF has a ...

Abstract: Determining appropriate phase-to-phase gap distances is critical to withstand phase-to-phase switching overvoltages in unconventional high surge impedance loading (HSIL) transmission lines.
