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…
Reconfigurable Superdirective and Superabsorptive Aperiodic Metasurfaces
Yongming Li, Xikui Ma, Xuchen Wang +1
In this paper, we present a general theory of aperiodic subwavelength arrays for controlling electromagnetic waves. The considered platform is formed by an array of electrically sm…
Going Beyond Perfect Absorption: Reconfigurable Super-directive Absorbers
Yongming Li, Xikui Ma, Xuchen Wang +1
In the context of electromagnetic absorption, it is obvious that for an infinite planar periodic structure illuminated by a plane wave, the maximum attainable absorptance, i.e., pe…
Simultaneous High-Efficiency Anomalous Reflection and Angle of Arrival Sensing in Reconfigurable Intelligent Surfaces
Mostafa Movahediqomi, Yongming Li, Grigorii Ptitcyn +2
In this work, we introduce reconfigurable intelligent surfaces designed to simultaneously perform reflection of single or multiple incident waves toward the receiver or receivers a…
Tunable Perfect Anomalous Reflection Using Passive Aperiodic Gratings
Yongming Li, Xikui Ma, Xuchen Wang +3
Realizing continuous sweeping of perfect anomalous reflection in a wide angular range has become a technical challenge. This challenge cannot be overcome by the conventional aperio…
