Abstract The characteristics of electromagnetic pulse produced by Photo-Conductive switches and Blumlein line under the bias voltage is studied by FDTD. The D’Alemberts formula is used to analyze the principle of Blumlein line. A total reflection border and the source method are given for the situation that Blumlein line worked under bias voltage. The SIBC is used to model the PCSs. The propagation of pulse is computed. The waveform of different time is given. The experiment result agrees with the numerical result well. The relation between geometry and output voltage of Blumlein line is studied.
