摘要

超表面是亚波长散射体的二维阵列[1]。它可以用表面阻抗来表征。受等效原理的启发，在超表面中引入表面磁阻抗，在激励下产生有效的表面磁电流[2]。证明了当表面电阻抗和磁阻抗为无源无损时，传输幅度和相位可以独立完全调谐[3]。

Reflectionless lossy metasurface for full control of electromagnetic wave transmission

The metasurface is a two dimensional array of subwave-length scatters [1]. It can be characterized by the surface impedance. Inspired by the equivalent principle, surface magnetic impedance is introduced into the metasurface to generate effective surface magnetic current under excitation [2]. It is proved that when the surface electric and magnetic impedance are passive and lossless, the transmission magnitude and phase can be tuned independently and fully [3].
