a The dispersion relation of this platform demonstrates a stationary inflection point frequency fSP which is shown by a dotted black line. b Logarithmic plot of the differential reflectance ΔR (blue dots) as a function of the frequency detuning \(\nu\) from the non-resonant exceptional point degeneracy frequency fSP. The black dashed line indicates the best fitting corresponding to a power law \(\Delta R\propto\left|\nu\right|^{0.7}\). The inset shows the formation of a cusp in the reflectance R spectrum, in the vicinity of fSP (vertical black dashed line). c Logarithmic plot of the differential reflectance ΔR (blue dots) as a function of the magnetic field detuning ΔH from the applied magnetic field strength \({H}_{{{{{{\rm{SP}}}}}}}\) where the order \(m=3\) non-resonant exceptional point degeneracy occurs. The black dashed line is the best fit \(\Delta R\propto\left|\Delta H\right|^{0.66}\).
