Experimental study of generic billiards with microwave resonators

In this work we study the eigenstates and the energy spectra of a generic b illiard system with the use of microwave resonators. This is possible due t o the exact correspondence between the Schrodinger equation and the electri c field equations of the lowest modes in thin microwave resonators. We obta in a good agreement between the numerical (exact) and experimental eigensta tes, while the short range experimental spectral statistics show the expect ed Brody-like behaviour in this energy range, as opposed to the Berry-Robni k picture which is valid only in the semiclassical region of sufficiently s mall effective Planck's constant.
