Abstract :
The proposed DF-FDTD method can be used to build a model for the transfer impedance. According to this transfer impedance model and the induced current of the outer conductor, the induced current and voltage of the inner conductor can be obtained by the transmission line (TL) model. This work can provide the theory support for the protection of the inner conductor from the EMP field.
