Background

In recent years, terahertz waves, which have become well developed as a link between millimeter waves and infrared light in the electromagnetic spectrum, are undoubtedly a new field of research, and have great value in all aspects. The frequency of the terahertz wave is 0.1-10 THz, and the corresponding wavelength is 0.03-3 mm. For a long time, due to the lack of an effective terahertz wave generation and detection method, the electromagnetic radiation property of the band is poorly understood compared with the traditional microwave technology and optical technology, so that the band becomes a terahertz gap in the electromagnetic spectrum. With the breakthrough of terahertz radiation sources and detection technologies, the unique and superior characteristics of terahertz are discovered and have great application prospects in material science, gas detection, biological and medical detection, communication and the like. It can be said that terahertz technology science is not only an important fundamental problem in scientific technology development, but also an important requirement for new-generation information industry and basic science development. The terahertz system mainly comprises a radiation source, a detection device and various functional devices. The terahertz absorber plays an important role as an important part of a terahertz detector.

The terahertz wave switch is an important terahertz wave functional device, has wide application prospects in terahertz wave application fields such as terahertz wave imaging, terahertz wave medical diagnosis, terahertz wave communication, terahertz wave space astronomy and the like, but is complex in structure, difficult to manufacture, high in price, large in loss and low in response speed. Therefore, a terahertz wave switch with a simple structure, convenience in manufacturing and high response speed is urgently needed to be researched to meet the requirement of terahertz practical application.
