概述太赫兹技术及太赫兹天线的发展状况,重点介绍太赫兹赋形面天线技术在太赫兹准光系统、太赫兹通信系统、太赫兹成像系统等领域的应用.赋形面技术主要基于能量守恒定律和等光程原理将出射的波束转换成要求的场分布.赋形反射面能够实现标准反射面不能实现的功能.因此赋形面技术将大大拓展现有的反射面天线在太赫兹波段的应用场景,并能提高太赫兹系统的幅度和相位特性.

This paper gives a brief review on the terahertz technology,with the emphasis on the development of shaped reflector antenna techniques. The applications of shaped reflector antenna techniques to terahertz quasi-optical system,terahertz communication system,and terahertz imaging system are discussed. Shaping technique can transform the output beam to desired field distribution according to the law of energy conservation and equal-optical path principle. Shaped reflectors can therefore extend the functionality of conic reflectors. Shaping technique will extend the applications of reflector antenna in terahertz range,and enhance the amplitude and phase performance of a terahertz system.
