Analysis of terahertz wave nonlinear reflection by an array of double silicon elements placed on a metal substrate

We demonstrate simulation results of nonlinear reflection of intensive terahertz radiation from a silicon-on-metal metasurface involving an excitation of a high-Q trapped mode resonance. Conditions are presented to observe the effects of bistability and hysteresis of nonlinear reflection.
