The dominant mode in closed circular groove guide   总被引:1,自引:0,他引:1  
The structure of closed circular groove guide is similar to that of open circular groove guide, but it can prevent energy from leaking out of the guide. In this paper, the dominant mode in closed circular groove guide is considered. The characteristic equation is derived and solved and the results are discussed.The Project Supported by National Natural Science Foundation of P. R.

A transition between rectangular waveguide and circular groove guide is described. The composite transition consists of two sections. It is theoretically designed to provide both mode matching as well as low reflection coefficient. The performance of the transducer is plotted.The Project Supported by National Science Foundation of P. R. China  相似文献
