Abstract

A dual function metasurface based on flip-chip Aluminium Gallium Arsenide (AlGaAs) PIN diodes is presented. Depending on the biasing state of the PIN diodes, the metasurface exhibits either a 1-bit reflection response or a transmission response. The design was optimized using the full 3D model of the AlGaAs PIN diodes. Simulations have been carried out using CST microwave studio to evaluate the performance of the dual function metasurface. The optimized metasurface demonstrates an average reflection loss of 0.3 dB and a transmission loss of 1.09 dB at 29 GHz. The corresponding simulation results were compared against both the simulated (obtained from a SPICE model developed in a circuit simulator) and measured S-parameters of the diodes. The transmission and reflection responses obtained at the operating frequency remain consistent across the three modelling approaches are presented and discussed.
