TL;DR: A low-profile holographic imaging system at millimeter wavelengths based on an aperture composed of frequency-diverse metasurfaces is demonstrated and computational methods and calibration approaches that enable rapid and accurate imaging performance are introduced.

TL;DR: In this paper, the authors presented a 3D computational imaging system based on a mode-mixing cavity at microwave frequencies, which encoded the scene information onto a set of frequency modes.

TL;DR: A microwave imaging system that combines advances in metamaterial aperture design with emerging computational imaging techniques is demonstrated and the potential of multisensor fusion is illustrated by integrating an infrared structured-light and optical image sensor to accelerate the microwave scene reconstruction and to provide a simultaneous visualization of the scene.

TL;DR: In this article, a dynamic metamaterial aperture was proposed for use in computational imaging schemes at microwave frequencies, which consists of an array of complementary, resonant metammaterial elements patterned into the upper conductor of a microstrip line.

TL;DR: It is argued that metamaterial antennas are a near ideal platform for implementing schemes at microwave frequencies and the tradeoffs governing the design and operation of each architecture are examined.
