Chirality-Assisted Geometric-Phase Metasurface with Independent Modulation of Phase and Amplitude

Chirality-assisted metasurface can independently modulate the phase and amplitude of electromagnetic waves, which have great application prospects in designing arbitrary modulated-phase metasurface with distinct wavefront manipulation. To further improve the transmission amplitude and reduce the sensitivity of incidence angle, this paper propose a chirality-assisted geometric-phase metasurface unit, which is designed to manipulate phase and amplitude independently and experimentally validated to generated high-order Bessel beam.
