I have a question regarding the coupling of a nanobeam photonic crystal resonator with a nearby bus waveguide using the side-coupled approach. Is it possible to use the EME solver in this case?

Furthermore, I am interested in measuring the quality factor in the transmission spectrum of the bus waveguide. The intrinsic quality factor of the resonator is over 1 million, so I'm wondering which solver would work better for this scenario: FDTD or EME?
