论文摘要
我们提出了一个（非触发）跨表面磁性镜面隔离器。该设备在一个方向的指定角度下以镜像作为镜像的波动，并在相反的方向上吸收它。元表面是根据双异型易感性张量合成的，其非肾脏驻留在正常成分中，并表现出混合电动电气，磁性电力性质。元粒子以晶体管加载的U形导电结构的形式实现。全波模拟和实验都证明了镜面隔离器的操作原理，隔离水平分别达到41和38 dB。该系统代表了涉及非交流正常敏感性的元表面的第一个实现，并且具有先前未报告的非转换类型。
We present a (nongyrotropic) metasurface magnetless specular isolator. This device reflects as a mirror a wave incident under a specified angle in one direction and absorbs it in the opposite direction. The metasurface is synthesized in terms of bianisotropic susceptibility tensors, whose nonreciprocity resides in normal components and exhibits a hybrid electric, magneto-electric nature. The metaparticle is implemented in the form of a U-shaped conducting structure loaded by a transistor. The operation principle of the specular isolator is demonstrated by both full-wave simulation and experiment, with isolation levels reaching 41 and 38 dB respectively. This system represents the first realization of a metasurface involving nonreciprocal normal susceptibilities and features a previously unreported type of nonreciprocity.
