摘要

本文报道了一种基于复合超材料结构的单向电磁吸能器。所提出的单向吸收器由不同的超材料板组成，其总厚度仅为工作波长的十分之一。线极化电磁波的能量可以沿一个方向传播，但沿相反方向传播时被完全吸收。设计了一个样机，并通过微波频率下的全波仿真验证了其能量传输和吸收效率的性能。该概念可用于设计新型非互易电磁器件和极化控制器件。

One-way electromagnetic energy absorber base on composite metamaterial slabs

This paper reports a one-way electromagnetic (EM) energy absorber based on a composite metamaterial structure. The proposed one-way absorber is composed of different metamaterial slabs with a total thickness of only one-tenth the operating wavelength. The energy of linearly polarized EM waves can propagate through such absorber along one direction, but be fully absorbed when propagating along the opposite direction. A proto-type example is designed and the performance of the energy transmission and absorption efficiency has been well verified through the full-wave simulation at microwave frequency. The proposed concept could find application in designing novel nonreciprocal EM devices and polarization control devices.
