  In this work we study the eigenstates and the energy spectra of a generic
billiard system with the use of microwave resonators. This is possible due to
the exact correspondence between the Schroedinger equation and the electric
field equations of the lowest modes in thin microwave resonators. We obtain a
good agreement between the numerical (exact) and experimental eigenstates,
while the short range experimental spectral statistics show the expected
Brody-like behaviour in this energy range, as opposed to the Berry-Robnik
picture which is valid only in the semiclassical region of sufficiently small
effective Planck's constant.
