Polarization Standing Wave Cavity Assisted By Anisotropic Structures

摘要

Waveguides in accordance with embodiments of the invention are disclosed. In one embodiment, a dual-mode circular waveguide includes a cavity, a first end wall including a first handedness-preserving metasurface positioned at a first end of the cavity, and a second end wall including a second handedness-preserving metasurface positioned at a second end of the cavity.
