【摘要】 本文提出了一种基于极化相关可以全空间调控幅度的极化转换超表面,采用耦合-波导-解耦的超表面结构,设计了反射和透射通道。入射的线极化波可以透射和反射,且同时实现极化转换,利用入射面上两个通道馈电点相对位置的变化,基于极化相关原理调整入射线极化波转换为透射波和反射波的功率分配,实现了从透射波与反射波功率1:1分配到全透射无反射状态的均匀变化。更多还原

【Abstract】 A kind of polarization conversion metasurface element is proposed in this paper to modulate the amplitudes of electromagnetic waves in full space based on the principle of the polarization correlation.The structure of the element proposed is coupling-waveguide-decoupling,and the element has two channels of reflection and transmission.The polarization states of the reflective and transmissive waves can be converted simultaneously.By manipulating the relative position of the two channel feed points on the incident surface,the power distribution of reflective and transmissive waves can be controlled,to achieve a continuous variation from 1:1 to the state of full transmission without reflection.更多还原
