Frequency-beam-scanning nonreciprocal transmissive polychromatic metasurface
Frequency-beam-scanning nonreciprocal transmissive polychromatic metasurface
We present the theoretical analysis and experimental demonstration of frequency-beam-scanning nonreciprocal transmissive polychromatic metasurface. Such a metasurface is composed of a frequency- and space-varying super-cells possessing engineered phases and magnitudes. The metasurface provides directive and diverse radiation beams, and the beams may be steered by changing the control direct current (DC) bias of the super-cells. Other interesting features include three-dimensional prism functionality with digitally controllable angles of refraction, and nonreciprocal power amplification.

Abstract
We present the theoretical analysis and experimental demonstration of frequency-beam-scanning nonreciprocal transmissive polychromatic metasurface. Such a metasurface is composed of a frequency- and space-varying super-cells possessing engineered phases and magnitudes. The metasurface provides directive and diverse radiation beams, and the beams may be steered by changing the control direct current (DC) bias of the super-cells. Other interesting features include three-dimensional prism functionality with digitally controllable angles of refraction, and nonreciprocal power amplification.
