Metamaterial Electromagnetic Wave Absorbers
TL;DR: The ability of the MPA to exhibit extreme performance flexibility will be discussed and the theory underlying their operation and limitations will be established and Insight is given into what the authors can expect from this rapidly expanding field and future challenges will be addressed.

Terahertz single pixel imaging with an optically controlled dynamic spatial light modulator
TL;DR: A single pixel terahertz (THz) imaging technique using optical photoexcitation of semiconductors to dynamically and spatially control the electromagnetic properties of a semiconductor mask to collectively form a THz spatial light modulator (SLM).

TL;DR: It is shown that electronically tuned DMAs can generate steerable, directive beams for traditional stripmap and spotlight SAR imaging modes, which eliminates the need for mechanical gimbals and phase shifters, simplifying the hardware architecture of a SAR system.

Enhanced Resolution Stripmap Mode Using Dynamic Metasurface Antennas
TL;DR: A new SAR mode of operation is proposed, which improves resolution while maintaining good SNR and a large scene size, and leverages the unique properties of dynamic metasurface antennas to subsample a large virtual beamwidth utilizing multiple small distinct antenna beams.
