Realization of Low-Complexity Reconfigurable Huygens’ Metasurfaces

An impinging wave incident on a Huygens’ meta-surface can be arbitrarily manipulated by inducing the electric and magnetic currents required by the equivalence principle along the surface. Reconfigurable Huygens’ metasurfaces have the potential of obtaining wideband tunable responses by incorporating tunable elements into the surface, making them suitable for applications requiring real-time reconfigurability. In this paper, we present the design of a unit cell in a low-complexity reconfigurable Huygens’ metasurface that requires fewer diodes and is simple to manufacture, compared to current implementations. Simulation results show that the designed unit cell has low insertion loss and linear phase profile over a wide bandwidth.
