Hi COMSOL-user,
I'm new to COMSOL. In the Tutorials I cannot find any example for the usage of the Lumped Port boundary condition as I need to (I might have missed some), so I decided to pulish my question here. I'm trying to simulate a twisted cable with two conductors (surrounded by insulators) like in the screenshot below. I want to add an alternating current with high frequency and I want to calculate the impedance of the cable and the radiation it emmits. I would prefer the transient solver if possible. Thanks for your answers in advance.
