| 摘 要： | We simulate the THz radiation＇s time domain waveforms of both the near field and the far field of a GaAs large aperture photoconductive antenna based on the current surge model. Because the micro-kinetic factors, such as transient state changes of current carrier＇s mobility and lifetime of current carriers, are taken into account in the calculation, we find out the influences of these factors on the THz radiation intensity by changing the above parameters. The results are of guiding significance to design of high-power photoconductive THz radiation antenna materials.
