All-Angle Scanning Leaky-Wave Antennas and Surface-Wave Routing by Reconfigurable Metasurfaces
Yongming Li, Xikui Ma, Viktar Asadchy +1
In this work, we show that propagating waves can be fully converted into surface waves and back using geometrically periodic arrays of simple electrically small metal elements load…
