Abstract
In a microwave transmission measurement the Green function of a stadium billiard was determined as a function of and for fixed . From this billiard wave functions were obtained including the sign, which was not available earlier. The propagator was obtained by Fourier transform of . It is shown that supplies a very suggestive picture of pulse propagation including pulse reconstruction by focusing effects. This can be considered as an experimental verification of a work of Tomsovic and Heller, who found that semiclassical dynamics can account for the quantum mechanical behavior of billiards over surprisingly long times.
