Abstract :
Silicon-process compatible metasurface was designed and tested in the infrared wavelength range. These metasurfaces show very high Q (>100), extreme chirality, and polarization conversion along with very low-loss operation. They show promise for sensing applications as well as spectrally selective CP thermal emitters.
