Dear brother,

I try to build Photoconductive Antenna using AC/DC physic (Electric Currents, to set DC voltage) and RF physic (Electromagnetics Wave Frequency Domain, to set femtosecond laser pump)..

When I applied voltage in AC/DC physic, the resultant electric field doesn't appear in results of RF physic, there is no coupling between those physics. So, I need to do this coupling to connect those physics together and get the right results.

Also, should I work in Time or Frequency domain

Thank you
