摘要:

超材料具有自然界材料所不具备的电磁参数,通过适当设计可实现对电磁波的调控。综述了超材料非对称传输器件的研究现状,分别介绍了电磁波非对称传输的基本原理, GHz、THz频段线极化波非对称传输器件及圆极化波非对称传输器件的研究成果。分析表明,基于超材料的非传输器件主要集中在微波波段,对太赫兹频段的研究较少,特别是在实验验证方面。最后讨论了超材料非对称传输器件的发展方向。

Abstract:

Metamaterials have many special electromagnetic characteristics which are not available in natural materials, and it can control electromagnetic wave by properly designing. Researches on metamaterial asymmetric transmission devices are reviewed. The fundamental principle of asymmetric transmission of electromagnetic wave, research achievements of asymmetric transmission devices with linear polarized characteristics in GHz and THz bands and devices with circularly polarized wave are introduced respectively. Analysis shows that metamaterial asymmetric transmission devices are mainly focused on the microwave band, few research is carried out in terahertz band especially in the field of experimental verification. Finally, the development trend of metamaterial asymmetric transmission devices is discussed.

Key words: electromagnetics, asymmetric transmission, metamaterial, terahertz, chirality, polarization
