Abstract

Terahertz (THz) waves, as electromagnetic radiation situated between microwaves and optical waves, possess distinct advantages including strong penetration capability, low photon energy, broad bandwidth, and fingerprint spectral characteristics, demonstrating significant application potential in the fields of communication, imaging, and sensing. This paper elaborates on multifunctional tunable terahertz metasurface waveplates that incorporate various tuning mechanisms including electrical, optical, thermal, mechanical, and chemical modulation to achieve dynamic multifunctional integration. These waveplates not only demonstrate efficient polarization conversion and beam manipulation across broad bandwidths, but also exhibit advantages of low loss, high efficiency, reconfigurability, and integration capability. Although current research still faces challenges including fabrication difficulties in low-frequency bands, relatively high loss in high-frequency ranges, and the need for improved response speed and tuning range of modulation mechanisms, the development and applications of dynamically tunable terahertz metasurface waveplates remain critically important, with expected breakthroughs in tuning range, response speed, performance optimization, and integration, thereby providing crucial support for advancing terahertz technologies.

多功能可调谐太赫兹超表面波片的研究进展

太赫兹（THz）波作为介于微波和光波之间的电磁辐射，具有穿透能力强、光子能量低、带宽宽、指纹光谱特性等明显优势，在通信、成像、传感等领域具有重要的应用潜力。本文详细介绍了多功能可调谐太赫兹超表面波片，它结合了各种调谐机制，包括电、光、热、机械和化学调制，以实现动态多功能集成。这些波片不仅在宽带上具有高效的极化转换和波束操纵，而且具有低损耗、高效率、可重构性和集成能力等优点。尽管目前的研究仍然面临着包括低频制造困难、高频损耗相对较高以及需要提高调制机制的响应速度和调谐范围等挑战，但动态可调谐太赫兹超表面波片的开发和应用仍然至关重要，有望在调谐范围、响应速度、性能优化和集成方面取得突破。从而为推进太赫兹技术提供关键支持。

期刊介绍： The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications. Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field. A journal of The Minerals, Metals & Materials Society.
