Dear Sir/Madam,

I searched through forum and cannot find the answer to my question.
I am trying to simulate electric and magnetic field between two copper parallel plates (2D axial symmetry).
Electrodes are connected to an RF generator with voltage amplitude of 400 V and frequency of 13.56 MHz.
I am trying by using Magnetic and Electric field module, but I don't know how to implement the voltage source.

Thank you,

Regards,
Grega

Gregor,

I think you can use a lumped port for this. You find examples in the model library.

Cheers
Edgar

Thank you for your help Edgar. But don't equations "behind" the lumped port use only stationary effects, without changing electric field (voltage)?

If you do a frequency domain study the port is supplied with a harmonic voltage according to the study settings, e.g. your 13.56 MHz.
