Space charge electrons transport a considerable fraction of current in magnetically insulated transmission lines (MITLs). When MITL has geometrical discontinuity, the interaction between the disturbed electrons and non-linearly coupled electromagnetic field makes their behavior difficult to predict. In this paper, the power flow through those MITLs is discussed using a particle simulation code and an analytical model. The results show that the space-charge electrons tend to maintain the effective impedance of the transmission lines, by changing their distribution and boundary of the space charge flow. Although a fraction of the space charge flow shunts the gap when the discontinuity is larger than the critical value, the total current upstream the discontinuity is still preserved.
