Hi, I want to design in practical a ring resonator on substrate like rogers rt duroid 5880. With those rings, I want to use some passive/active components as well in order to improve performance. This would be helpful if someone guide me how to do this in Comsol. I can design ring embedded on substrate in comsol, but component like resistors, capacitors or inductors to add with that ring, I need suggestions.
