This paper describes a nonlinear Fresnel zone plate reflector designed to operate at 2.8GHz. The alternating Fresnel zones of the reflector are made from two different nonlinear metamaterials: one that reflects like a short circuit at low incident power levels and another that reflects like an open circuit. Both metamaterials transition from highly reflective to highly transparent as the incident power increases. Additionally, as the metamaterials transition to their transparent state the phase difference between their reflection coefficients decreases substantially, causing the reflector to lose its focusing capabilities. In this way, the field observed at the focus is reduced both as a consequence of the metamaterials becoming transparent as well as the reflector defocusing.
