I am trying to create a dipole antenna model where I need to place a port at the interface where two cylindrical surfaces overlap. I aim to calculate the S-parameters in both underwater and air environments, as shown in the attached figure.
When I attempt to create the dipole using a line, I encounter an error stating that the connection point cannot be found, so I opted to construct the dipole using cylinders instead. However, I am unsure how to correctly place a port at the interface of these two cylinders. Could someone please guide me on how to set up the port in this configuration?
