Design of nonlocal Huygens’ meta-lens. a Schematic diagram of the IRU. b SEM image of the fabricated sample. The scale bar is 1000 nm. c Experimental and simulated transmission TRL spectra. Red and blue areas indicate the bandwidth of q-BIC and MDR, respectively. d Dependences of transmission TRL (color map) and phase φRL (black spheres) on the rotation angle of IRU. Phases are extracted from the corresponding resonant wavelength
