Since the dominant mode combiner as the injection signal source can oscillate only in TM_<010>-mode, injection excitation of the desired mode in the oversized cavity facilitates undesired modes suppression as well as combine the available power of all the devices in both cavities. To study the operating characteristics of this combiner, it is necessary to understand the coupling field in the cavities and construct suitable equivalent circuit model. In this paper, axial symmetric FEM field analysis is applied on the reduced and loss free double cylindrical cavity eliminating the active devices and the output probes. Then the configurations of the coupling circuit are discussed.}, pages = {39--45}, title = {二重円筒空胴電力合成器の結合電磁界}, volume = {17}, year = {1994} }
