Reconfigurable Sparse Metasurface: Beamforming Beyond Phase Gradient Heuristics

Abstract

We present a design of a reconfigurable sparse metasurface operating at microwave frequencies (X-band). The operating principle of the metasurface does not rely on established phase gradient along its surface, it allows one to overcome common limitations of the phase-gradient-based devices. Instead, we have developed a rigorous microscopic approach that allows one to take into account the interaction between the neighboring elements and engineer the individual response of each scatterer to meet a required functionality. By varying the applied bias voltage, we experimentally demonstrate beam steering as well as generation and steering of two (and more) beams with a single feeding horn antenna.
