Eigenoscillations near cascade of thin disks between the pair of parallel planes

Eigenoscillations near cascade of thin disks between the pair of parallel planes are studied. The sufficient conditions of existence for eigenoscillations are found. The dependence of eigenfrequencies on the geometric parameters of structure is investigated. It is shown that the frequencies of eigenoscillations of given structure are discrete and they formed a bundle of resonance frequencies which is under specific conditions act as a continuous band of resonance frequencies. The number of resonance bundles is calculated.
