Metasurface-Enabled Antiparallel Dual-Beam Rectangular-Waveguide Antenna
, 2020 We propose a metasurface structure integrated at the aperture of a flanged rectangular waveguide to produce dual-beam radiation. The dual beams are anti-parallel in an orientation and perpendicular to the boresight direction. The metasurface is backed by
