Figure 15
From: Experimental Microwave Scattering in Polygonal Billiards
Symbols: Measured cumulative spacing functions in the rectangular billiard with the indicated values of temperature and antenna height. Blue (red) solid line is the Poisson (Wigner) theoretical result. The solid black line is a plot of the semi-Poisson function \({I}_{{\rm{SM}}}(s)=1-[(1+2s)\,\exp (\,-\,2s)]\), for comparison.
