Wideband dynamic metasurface antenna performance with practical design characteristics
Joseph M. Carlson, Nitish V. Deshpande, Miguel Rodrigo Castellanos +1
Dynamic metasurface antennas (DMA) provide low-power beamforming through reconfigurable radiative slots. Each slot has a tunable component that consumes low power compared to typic…
