Millimeter-Wave Compressive Imaging with Metamaterial Antennas

Reynolds-millimeter-2We have developed novel compressive imaging approaches in the millimeter wave bands (18-26 GHz, 85-110 GHz) using metamaterial antennas. The metamaterial antennas are designed to exploit extreme frequency diversity in their radiated modes to enable rapid single-shot image reconstruction from sparse measurements. Applications include spaceborne imaging radars as well as indoor personal security.
