摘要：
Based on the particle-in-cell(PIC) simulation, a new method is proposed to compute the equivalent inductance and capacitance of magnetically insulated transmission line(MITL). Two scaling factors are introduced into the expressions for the equivalent inductance and capacitance of the coaxial MITL, which are derived from the laminar flow model. The voltage-dependent expressions of the two factors are obtained by fitting the PIC simulation results. The rescaled equivalent capacitance and inductance can match the PIC simulation results well, thus the results obtained can be used for the circuit modeling of MITLs.
