Abstract: The metasurface can provide beam deflection by providing phase gradient. In this work, a single-layer small size transmission-type metasurface is used to generate a deflect beam in the ...

Abstract: We investigated the effects of weak turbulent seawater on the propagation of orbital angular momentum (OAM) spiral modes carried by shift and deflection Bessel Gaussian beams. The analytic ...
