How to excite all possible modes in a micro resonator

HI,

I am using Frequency Domain in WaveOptics Module to find resonant frequencies of a 3D micro resonator. The range of wavelength I search is in between 400nm to 600nm with a step of 1nm. However, the resonant frequencies I obtained from the Intensity Spectrum are not agree with the ones I obtained using EigenFrequency Study.

I noticed that in COMSOL examples, it says 'the excitaion should be as isotropic as possible, so it can excite all possible mode'. What does isotropic mean? If I use Edge Current as Excitation source, where should I excite on the resonator? Is there any guidence that I can follow?

Thanks a lot!

Best regards
