Abstract
Terahertz reconfigurable metasurfaces for beam steering have long-standing suffered from non-ideal amplitude and phase modulation. Herein, via an effective bottom-up solution combining optimizations of the array encoding efficiency and array-level coding, a 1-bit THz HEMT-controlled metasurface with minimized amplitude-phase quantization error and enhanced gain has been achieved.
