In this paper, we propose the design of a metasurface that can achieve three functions in different frequency bands. The proposed metasurface is composed of two kinds of unit cells which are designed on the basis of the spatial k-dispersion engineering of spoof surface plasmon polaritons (SSPPs). By arranging these two kinds of unit cells in the chessboard configuration, the three functions of transmission, anomalous refraction and absorption can be integrated into one metasurface. High transmission and strong absorption can be achieved in 2.0-9.0 GHz and 12.6-20.0 GHz, respectively. Meanwhile, anomalous refraction can be achieved in 10-11.7 GHz due to forward scattering cancellation of two unit cells. To verify the design, a prototype was fabricated and measured. The measured results are consistent with the simulation ones. The metasurface can integrate multiple functions into one aperture and therefore has potential application values in multifunctional microwave devices such as shared-aperture antennas, etc.

基于欺骗表面等离振子极化子的三功能超表面。

在本文中，我们提出了可以在不同频带上实现三种功能的超颖表面的设计。拟议的超表面由两种单位晶格组成，它们是根据空间k设计的欺骗表面等离振子极化子（SSPPs）的分散工程。通过将这两种单位晶胞布置成棋盘结构，可以将透射，异常折射和吸收这三种功能整合到一个超颖表面中。在2.0-9.0 GHz和12.6-20.0 GHz分别可以实现高传输和强吸收。同时，由于两个晶胞的前向散射消除，因此可以在10-11.7 GHz内实现异常折射。为了验证设计，制造并测量了原型。测量结果与仿真结果一致。超表面可以将多个功能集成到一个孔中，因此在诸如共享孔径天线等多功能微波设备中具有潜在的应用价值。
