Compressed Sensing Imaging Based on Microwave Frequency-Diverse Metamaterial Apertures

In this paper, a metamaterial aperture antenna consisted of metal/insulator/metal (MIM) resonant elements is designed for microwave compressive sensing imaging. Such resonant-based device enables the radiation patterns of aperture antenna strongly modulated by frequency, and thus the computational imaging can be realized by scanning frequency such frequency-diverse system. Based on such metamaterial apertures, we demonstrate compressed sensing imaging in microwave region.
