Looks like they did simulate it, and the experimental results differed from the simulation due to number of harmonic terms used: βTo obtain quantitative agreement between the phase model (Eq. 3) and the experiment, additional terms in the harmonics of the magnitudes would need to be included in the phase model.β Which I suppose implies that very weak, distant harmonics might play an important role in these patterns.

Also an earlier paper from the same group that discusses infeasibility of other approaches: https://authors.library.caltech.edu/81293/1/acs.nanolett.7b0...
