Intelligent meta-imagers: From compressed to learned sensing

Witrynathe metamaterial was shifted, introducing a significant inten-sity modulation at the resonance frequency. A 20% shift in the metamaterial resonance frequency was obtained when varying the optical power from 0 to 500 mW at an optical wavelength of 800nm, leading to a 70% modulation depth at 1.06 THz.
