Published in 2020 at "Applied Sciences"

DOI: 10.3390/app10207219

Abstract: In this paper, a generation method procedure based on a reflective metasurface is proposed to generate multiple pseudo Bessel beams with accurately controllable propagation directions and high efficiency. Firstly, by adjusting the miniaturized unit cell… read more here.
