We analyze the spectral properties of various quantum pseudointegrable
billiards (rhombus, gnomon, deltoid) and link them to the genus of th
e invariant surface of the corresponding classical model. Numerical in
vestigations of the quantum billiards are completed by an experimental
study of microwave resonators. Absorption spectra of microwaves in ''
L-shaped'' resonators are measured and the distributions of eigenfrequ
encies are investigated.
