A Multifunctional Chiral Metasurface with Asymmetric Transmission and Linear-Polarization Conversion
提出了一种多功能手性超表面来实现不对称传输(Asymmetric transmission,AT)和线偏振转换(Linear-polarization conversion,LPC).设计的超表面由十字剑状形状和单元电池下侧的两个孔组成.在8.3～10.4 GHz频段,实现了 90%以上的AT效率,并且相同的手性超表面将线偏振波高效地转换为正交波.对于LPC,偏振转换率(Polarization conversion ratio,PCR)大于95%.对于AT和LPC操作,所提出的超表面对于高达60°的电磁(Electromagnetic,EM)波入射角都是稳定的.
In this paper,a multifunctional chiral metasurface is presented to achieve asymmetric transmission(AT)and linear-polarization conversion(LPC).The designed metasurface consists of a cross swords-like shape and two holes in the lower side of the unit cell.In the frequency band from 8.3 GHz to 10.4 GHz,AT is realized with more than 90%efficiency and the same chiral metasurface transforms linear polarized wave into its orthogonal counterpart with high efficiency.For LPC,the polarization conversion ratio(PCR)is greater than 95%.The proposed metasurface is stable against the incident angles of striking electromagnetic(EM)waves up to 60° for both operations of AT and LPC.
