Hello Dear Readers,
This is my first forum entry -- please be patient with my unexperienced discussion skills.
I am working on Silicon-Organic Hybrid-Modulators and its modulation efficiency. For the electrode structure, I am using CPW.
My problem I am trying to troubleshoot since many days is that in the RF-Module, I am not able to set a voltage on the (center) conductor of the CPW and thus be able to alter the electric field in the gap between the conductors in dependence of the applied voltage. I am trying to run a Mode Analysis Study with RF Module (emw) and Electrostatics (ES)/ Electric Currents (EC) interfaces of the AC/DC Module. In the ES or EC interface, I am applying Electric Potentials and Grounds on the respective conductors. But still, the Mode Analysis Study computes the Electric Field in the gap independently of the applied voltage in the ES/EC inteface -- the Electric Field in the gap is the same at 1V at the center conductor as at >>1V...
May I ask you for your help, how to overcome this problem? Is there any method to apply a voltage on a conductor (of a CPW) and compute the RF-Electric Field (in the gap between the conductors) and the mode profile with respect to the applied voltage?
I sincerely hope for your help. Thank you very much!
