A metamaterial aperture operating as a leaky waveguide with resonating metamaterial irises can sweep its operation frequency to modify its complex field pattern with no moving parts. By randomly distributing the metamaterials' resonance frequencies, we show the aperture can generate random illumination patterns well suited for compressive sensing. In this way the aperture utilizes the physical layer to avoid redundant measurements in the image reconstruction process. © 2013 IEEE.
