Metasurfaced Reverberation Chamber [PDF]
Scientific Reports, 2018 The concept of metasurfaced reverberation chamber (RC) is introduced in this paper. It is shown that by coating the chamber wall with a rotating 1-bit random coding metasurface, it is possible to enlarge the test zone of the RC while maintaining the ...

Metasurface Photodetectors [PDF]
Micromachines, 2021 Photodetectors are the essential building blocks of a wide range of optical systems. Typical photodetectors only convert the intensity of light electrical output signals, leaving other electromagnetic parameters, such as the frequencies, phases, and polarization states unresolved.

A True Metasurface Antenna [PDF]
2016 IEEE International Symposium on Antennas and Propagation (APSURSI), 2016 AbstractWe present a true metasurface antenna based on electrically-small resonators. The resonators are placed on a flat surface and connected to one feed point using corporate feed. Unlike conventional array antennas where the distance between adjacent antennas is half wavelength to reduce mutual coupling between adjacent antennas, here the distance ...
