Hello brothers,

I try to build a Photoconductive Antenna.. I tried to set a femtosecond laser pump in Time Domain... This laser hits the gap between electrodes..Then we will get a Terahertz radiation at the back of the substrate... I did the following:

1) At first, I tried to use the equation of Figure-1 that attached

2) Then, I tried to set the integration of denominator that in Figure-1.. it is shown in Figure-2

3) Finally, I try to set the equation of Figure-1 to get results as it is shown in Figure-3 and Figure-4

I get no results !!

I don't know what mistakes that I did

Thank you brothers
