Dear all,

After reading the following post, I would still have a question, please: https://www.comsol.com/forum/thread/344681/modeling-magnetron-antenna-connected-to-rectangular-waveguide

In the case I wish to model only the waveguide launcher and the magnetron antenna (the waveguide launcher whose picture has been attached in the previous post would be the furnace/resonant cavity itself where I would include some liquid to heat, small cube in my snapshot), how should I model the magnetron antenna? As far as I understood, it should be a coaxial port in the RF module, but not sure how to set the boundaries (please see attached picture, MPH file too big).

Thanks in advance,

Kind regards,

Fabio A.
