Abstract
First results on microwave billiards with broken time reversal symmetry are presented. The billiards are quasi two dimensional with an attached microwave isolator acting as a unidirectional transmission line. Spectral level dynamics was studied by changing the billiard length. For all spectral properties observed, i.e., nearest-neighbor distance, asymptotic curvature, and closest-approach distance at avoided crossings, we have found behavior characteristic of the Gaussian unitary ensemble.
