The exponentially decaying nature of evanescent waves renders it difficult to capture, extract and engineer the wealth of energy and information that they can carry. Utilizing the out‐of‐plane electric dipoles and in‐plane magnetic diploes produced by a bianisotropic C‐aperture metasurface, in this work, it is shown that evanescent waves can be effectively molded. More specifically, it is demonstrated that the phase, polarization state or beam profile of the emission from evanescent waves can be controlled via the orientation of C‐aperture nanostructures. The work opens a new avenue for metasurfaces to work in the critical near‐field region to efficiently harness evanescent waves, and promises many potential applications, including on‐chip free‐electron light sources, tabletop particle detectors and near‐field energy harvesting.

利用各向异性的超曲面来控制E逝波

van逝波的指数衰减特性使其难以捕获，提取和工程化它们所携带的大量能量和信息。利用由各向异性C孔径超表面产生的平面外电偶极子和平面内磁偶极子，这项工作表明，e逝波可以有效地模制。更具体地说，已证明that逝波发射的相位，偏振态或光束轮廓可以通过C孔纳米结构的取向来控制。这项工作为超表面在关键的近场区域工作以有效利用e逝波开辟了一条新途径，并有望实现许多潜在的应用，包括片上自由电子光源，台式粒子探测器和近场能量收集。
