Research Progress of Metamaterials for Terahertz Applications
摘要
太赫兹波和电磁超介质是电磁学领域关注的热点。太赫兹波与电磁超介质相互作用可以实现对太赫兹波的操纵和调控,有望填补“太赫兹空白”。介绍了太赫兹波段电磁超介质的研究进展,包括电磁超介质电磁性能可调谐的实施途径,电磁超介质在太赫兹功能器件方面的应用(调制器/开关、传感器/探测器、滤波器、偏振元件和吸波器),太赫兹波段表面等离子体电磁超介质,非金属太赫兹电磁超介质的实现以及太赫兹电磁超介质的制备。对电磁超介质可能形成的太赫兹器件及其物理机制进行了充分的阐述,并基于研究现状提出一些今后的研究方向和发展前景。
Abstract
Both terahertz (THz) electromagnetic wave and metamaterials are hot topics in electromagnetics research. Metamaterials operating in the THz range have achieved great successes in filling in the so-called “THz gap” due to its ability to control and manipulate electromagnetic waves. A comprehensive introduction to the progress of metamaterials at THz frequencies is given including the tuning strategies of electromagnetic response in metamaterials, metamaterials-based THz functional devices such as modulators/switchs, sensors/detectors, filters, polarimetric components, and absorbers etc., THz plasmonic metamaterials, nonmetallic structure to implement THz metamaterials as well as the advancements in fabricating THz metamaterials. It presents not only the metamaterials for THz applications but also their underlying mechanisms. Possible future directions in this field are also proposed.
