  • Abstract
    A periodic resonant texture can transform a conductive sheet into a high-impedance surface. By adjusting the resonance frequency using varactor diodes, the surface impedance and the reflection phase are tuned. The reflection phase can be varied across the surface, to create an electronically tunable phase gradient, which can steer a reflected beam in two dimensions.
