The Conduction Current and Displacement Current in a Terahertz Antenna

A semiclassical Monte Carlo model is presented to study the time-varying conduction current and displacement current in a Terahertz photoconductive antenna after photoexcitation. We analyzed conduction current and displacement current in a biased GaAs photoconductive antenna after fs laser pulse excitation as a function of bias voltage, pump pulse energy. While we analyzed conduction current and displacement current contribute on THz wave radiation. The simulation results show that the light-intensity dependence mainly influences the pulse amplitudes of the conduction current and the displacement current and THz wave. At the same lightintensity, higher bias field gives larger conduction current. The simulation results show that conduction current and displacement current are source of THz waveform radiated by bias photoconductive current.
