Probability distributions of normalized eigenfrequency spacings for TE modes in different parts of the spectrum: I — below the pseudo gap (a), V — above the pseudo gap (b), III — inside the pseudo gap (c). Panel (d) shows the probability of having s < 0.1, which can serve as a measure of eigenfrequency repulsion, for TM and TE modes as a function of randomness α.
