As a class of transmissive surfaces, Huygens' metasurfaces have attracted much attention in recent years due to their abilities to efficiently manipulate transmitted waves. However, the study of dual-polarized Huygens' metasurfaces using vialess double-layer elements has not yet been reported. To ...
In this paper, an anisotropic coding metasurface is proposed to achieve dual-mode vortex beam generator by independently manipulating the orthogonally linearly polarized waves. The metasurface is composed of ultrathin single-layer ground-backed Jerusalem cross structure, which can provide complete and inde...
(24) The inequalities (23) and (24) limit the performance of a metasurface designed to manipulate the light's polar- ization. For example, the maximum efficiency of a transmissive metasurface half-wave plate which rotates the polarization of a linearly polarized beam by 90 degrees, and is ...
We propose a Huygens source unit cell to develop an ultrathin low-reflection metasurface, which could provide extreme controls of phases of the transmitted waves. Both electric and magnetic currents are supported by the proposed unit cell, thus leading to highly efficient and full controls of phase...
Here, we proposed and designed Huygens' metasurfaces that can efficiently manipulate linearly polarized light to perform beam focusing (73% transmission efficiency for cylindrical lens and 68% transmission efficiency for aspheric lens) at near-infrared wavelengths. Additionally, the most significant ...

We present a set of universal relations which relate the local transmission, reflection, and polarization conversion coefficients of a general class of non-magnetic passive ultrathin metasurfaces. We show that these relations are a result of equal forwar
