Abstract

        While antennas and electromagnetic waves have been applied in every corner of modern wireless communications, it is becoming increasingly interesting to develop novel techniques for the manipulation of electromagnetic beams through reconsidering the fundamental physics. Metasurfaces, a kind of two-dimensional subwavelength artificial electromagnetic structures, offer new opportunities for controlling the amplitude, phase, and polarization of electromagnetic waves at the interface. These techniques have shown the prospect of generating and manipulating electromagnetic beams of various forms within a deeply subwavelength scale, which is especially useful in novel antennas designs and compact RF devices or systems. In this talk, I will present the recent achievement of high-efficiency metasurface lenses in our group. This includes broadband Luneburg lens for full-angle beam scanning and highly efficient generation of Bessel and OAM beams, and electronically reconfigurable transmissive array for beam scanning.
