Dynamic characteristics of long magnetically insulated transmission line

The relationships between voltage and current, self-limited flow and loss front propagation speed of long MITL were studied based on particle-in-cell simulation. Different MITL models which were established under the steady-state assumptions were compared. Mendel model is more accurate than parapotential model and collisional model when depicting the relationship between long MITL voltage and current. Rescaled model is more accurate than Mendel model and parapotential model when computing the anode current at self-limited flow of long MITL. The loss front propagation speed is variable along power flow direction in long MITL, the speed is related with rise rate of input voltage.
