中文摘要:对于亚毫米波或太赫兹系统而言,关键问题是功率源的输出功率非常小。 功率合成技术是增加输出功率的有效方法。 然而,在微波和毫米波段中使用的常规功率合成方法(例如电路级合成或波导内空间合成)在亚毫米波波段因损耗高及难以加工等因素而受到制约。 本文提出了一种基于准光学技术的波束功率合成方法。 它具有损耗低,合成效率高,相对容易制造的优点。本文给出了分析,仿真和实验结果,并得到高的输出合成效率。

Approach of beam power combining at sub-millimeter waves
Abstract:Key problem of sub-millimeter waves or terahertz system is the very small output power of the source. Power combining technology is a suitable approach to increase the output power. However the conventional power combining methods used in microwave and low millimeter wave bands such as circuits combining or waveguide spatial combining all suffer from the higher loss and difficult for manufacture and so on at sub-millimeter waves. In this paper an approach of beam power combining based on quasi-optical technology is proposed. It has advantages of low loss, high combining efficiency and relative easy for manufacture. The analysis, simulation and experiments results are presented. High combining efficiency has been obtained.
