亚毫米波是正在开拓中的电磁新波段,人们对这一波段的兴趣正日益增高。然而,直到最近,亚毫米波的传输、测试技术主要还是采用光学的技术——准光技术。本文简要介绍亚毫系波准光技术的发展概况,内容包括材料,准光元、器件及常用的准光测试系统,并展望了今后亚毫米波技术的发展。
Submillimeter waves are a new electromagnetic band that is under development and interest in this band is increasing. However, until recently, the transmission of sub-millimeter waves, the main test technology is the use of optical technology - quasi-optical technology. This paper briefly introduces the development of sub-millimeter wave quasi-optical technology, including materials, quasi-optical elements, devices and commonly used quasi-optical test systems, and looks forward to the future development of sub-millimeter wave technology.
