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 overcome this challenge, herein an ultrathin Huygens’ metasurface composed of only double‐layer elements without vias is proposed to achieve high transmission and near 360° phase shift for dual polarization. Based on induced magnetism, the top and the bottom elements act as both an electric dipole and a magnetic dipole, inducing the orthogonally electric and magnetic current simultaneously. Then their interaction excites the Huygens’ resonance. As an example of an application, a dual‐polarized Huygens’ meta‐lens is prepared that exhibits excellent antenna performance. Dual‐polarized Huygens’ metasurfaces based on induced magnetism offer extra opportunities for efficient transmitted wave manipulation in metasurfaces.

超薄双极化惠更斯的超颖表面：设计和应用

作为一类透射表面，惠更斯的超颖表面由于具有有效操纵透射波的能力，近年来受到了广泛关注。但是，尚未报道使用无孔双层元素对双极化惠更斯超表面的研究。为了克服这一挑战，本文提出了一种仅由双层元件组成而没有过孔的惠更斯超薄超表面，以实现高透射率和接近360°的双极化相移。基于感应磁场，顶部和底部元素同时充当电偶极子和磁偶极子，同时感应正交的电流和磁电流。然后他们的互动激发了惠更斯的共鸣。举例来说，制备出了具有出色天线性能的双极化惠更斯元透镜。基于感应磁场的双极化惠更斯超颖表面为超颖表面中的有效透射波操纵提供了额外的机会。
