Hi there,
I am relatively new to COMSOL, I am trying to model how the magentic field inside a resonator cavity oscillates within one wavelength of a microwave source applied to the cavity, as if I am following the curve of a sine wave. I'm not sure how to do this. Could this be helped? I've tried making a time dependent study and setting it to the period of the chosen frequency but the field does not change with time, I aslo tried splitting it up into real() and imag() plots as I heard COMSOL only uses absolute values but this did not change anything either. Any help would be greatly appreciated.
Thanks.
