Description

technical field [0001] The invention relates to the field of microelectronics and terahertz metamaterial functional devices. Background technique [0002] Terahertz wave refers to the electromagnetic spectrum with a frequency of 0.1-10THz. It is in the cross field of electronics and photonics, and it is the last electromagnetic wave band that has not been fully developed by human beings. Compared with electromagnetic waves in other frequency bands, terahertz waves have unique properties such as high transmission, broadband, and low energy, which make terahertz technology have great scientific value and vast potential in many high-tech fields such as large-capacity communication, biological imaging, and security inspection. application prospects. With the rapid development and initial commercialization of terahertz technology, the demand for flexible tunable terahertz functional devices is becoming more and more urgent, which also accelerates the research and exploration of ...
