| Abstract: | The experimental results by using an all solid insulation protection with Si GaAs photoconductive switches with microstrip line electric induction output as high power ultra fast electromagnetism pulse microwave source are reported. The nonlinear properties of initiation, sustain and recovery process displayed by the semiconductor photoconductive switches are summaried. The principle and performances of ultra fast photoconductive switches and application of ultra fast electromagnetism pulse sources to UWB are described in this paper. |
