Dual Circularly Polarized Metasurface Antenna Based on Inward and Outward Surface Wave Duplexing

This article proposes the design and numerical validation of a dual-polarized metasurface (MTS)-based antenna, in which the two polarizations share the same circular aperture. The design exploits the interaction of duplexed inward- and outward-traveling surface waves (SWs) with an unwinding spiral M...
