1) tweak for higher precision settingsn2) material and feature roughness can prevent achieving perfect resultsn3) more discontinuities can produce more modes, therefore completely incorrect frequency may be a result of hitting a wrong mode. Therefore define more modes to search in a wider range. Sweep the phase at coupled boundaries for seeing the exact dispersion (i.e. examine not the resonator, but the equivalent waveguide first).n
