| 摘 要： | 近年来, 随着太赫兹科学技术的发展, 越来越多的科学家向太赫兹间隙这一传统空白领域发起挑战. 其中, 人工电磁媒质因为能够设计太赫兹波段中紧缺的功能器件而受到广泛关注. 近年来, 对人工电磁媒质尤其是太赫兹方面的研究进展突飞猛进. 人工电磁媒质的性质不仅仅由其构成材料决定, 更与其结构单元的形状和空间排布密切相关. 本文介绍了人工电磁媒质在太赫兹波段的发展、原理、设计和应用, 并着重介绍完美吸波器和人工表面等离激元, 为太赫兹波段功能器件的研究提供了参考, 并对可能的发展方向予以展望.

| Abstract: | In the past decades, terahertz metamaterials have attracted considerable attention due to the capability of realizing essential terahertz functional devices and potential applications in sensing, imaging, spectroscopy and monitoring. In this review, we first present a brief introduction to the theory and development of terahertz metamaterials, and then focus on some terahertz devices including both triple-band and broadband metamaterial absorbers, the spoof surface plasmon polaritons (SPP) waveguides, the SPP bend, the SPP beam splitter, and the SPP ring resonator. The metamaterial absorbers are fabricated and measured in THz band, while the SPP devices are verified through numerical simulations. All the designs are easy to fabricate and favorable for practical applications. |
