Field-circuit co-simulation of the Marx generator

A full wave field-circuit co-simulation method is employed to characterise the time domain behaviour of the Marx generator. Radiation and conduction effects are fully considered. Results from the co-simulation and the circuit simulation are compared; it can be found that the field-circuit co-simulation provides complete information of the system which includes the radiation effect and the mutual coupling in space. The radiated field strength is important when designing the shielding room which is used to protect the measurement instruments in practice.
