The lower row in Figure presents simulations for the same particles as in the upper row, using the same parameter set, except for using ϵ class in the shell permittivity. In all cases, the additional dye peak emerges, both in the Mie-Gans (dashed red lines) and the FEM approach (dotted dark red lines). As predicted previously, the rogue resonance becomes more pronounced for smaller particles. In the HQM the spurious peak is suppressed by increasing power broadening.
