Abstract

Abstract

The vacuum part of the transverse section of this configuration is composed of 12 petal-like periods, and each period is composed of two basic transmission line configurations: parallel plates and coaxial arcs. The overall outline of this configuration effectively increases the electrode area, which greatly reduces the inductance of the transmission line, so that a lower impedance can be obtained by using a single-layer magnetically insulated transmission line,which avoids the complex PHC structure and the loss of the magnetic null region caused by the multi-layer bus structure. The electromagnetic field distribution, inductance, capacitance, and impedance of the two basic configuration units are calculated separately, and then the electromagnetic characteristic parameters of the petal-shaped magnetic insulated transmission line are calculated and analyzed as a whole. At the same time, the cold cavity characteristics of the transmission line are analyzed through numerical simulation, the impedance value and electromagnetic field distribution of the transmission line are obtained, and the numerical simulation results are compared with the theoretical calculation values for verification and analysis.
