毫米波、亚毫米波是电磁波频谱中正在发展中的一个波段。电磁波的发展迄今已有一百余年的历史。作为开端的是电磁波理论的提出和证实。其后各波段的发展,以产生和放大讯号的有源器件及传输讯号的无源器件为条件,而以应用技术为推动力。毫米波、亚毫米波大约从七十年代起开始发展,相对论相位群聚的回旋管提供了新的有源器件,鳍状线、介质波导等提供了无源器件,精确制导、扩频技术、材料研究等应用推动了发展。国际上毫米波与亚毫米波技术的发展,反映于一年一度的国际红外与毫米波会议(ICIMW)。此会议前十三届的焦点,都是基础技术、讯号的产生及波谱学,而从1989年的第十四届会议起,增加了新的焦点一技术应用,除军事应用以外,大城市中的汽车拨号电
Millimeter wave, sub-millimeter wave electromagnetic wave spectrum is being developed in a band. The development of electromagnetic waves has been a hundred years of history. As a starting point, the theory of electromagnetic wave was proposed and confirmed. Subsequent development of the band, to produce and amplify the signal of the active devices and signal transmission of passive devices as conditions, and the application of technology as a driving force. Millimeter and submillimeter waves have been developed since the 1970s. The gyroscopes for the relativistic phase agglomeration provide new active devices, finned lines, dielectric waveguides, etc., providing passive components, precision guidance and spread spectrum techniques, Applications such as material research drive development. The development of millimeter-wave and sub-millimeter-wave technologies internationally is reflected in the annual ICIMW. The focus of the thirteenth session of the conference was basic technology, signal generation and spectroscopy. Since the fourteenth session in 1989, a new focus has been added to the application of technology. In addition to military applications, Car dial phone
