Analysis and calculation of transmission efficiency of magnetically insulated transmission lines

Based on the numerical simulation results in time domain, the characteristic of the power loss caused by the emitting electrons in the different phases of establishing the magnetic insulation is discussed in this paper.The loss is caused by the electrons losing to the anode and the movement of the electrons in the magnetic insulation. The corresponding impact factors to the loss are analyzed, which are the length and the radius ratio of the transmission line, the peak pulse voltage and the time-varying rate of the input pulsed power. By analyzing the values and the characteristics of the loss, and the corresponding electron distributions in different periods with different pulse excitations, a staged model is proposed to calculate the total transmission efficiency, which divides the entire
