Phase of port in RF

I am trying to set up a boundary condition on a cube in a 3D RF simulation such that there is always a maximal magnetic field amplitude in the center. I have tried to accomplish this by playing around with the phase setting in the port boundary condition, but it does not seem to change anything no matter the order of the number I put into it. Does anyone know a way to accomplish this? I am rather new to FEM methods, so please forgive me if I am missing something basic.
Thank you,
Jon

This problem has probably been solved a long time ago, but I just bumped into it. The answer seems to be that Port phase is not active for port types Numeric and Coaxial. According to the documentation: "The Port phase field in the previous section has no impact for this mode type because the phase is determined by the entered fields." As I use Numeric, I will look for another way of setting the phase of the field, which currently flips 180 degrees randomly.
