ANALOGY IN INTERACTIONS OF ELECTRONIC BEAMS AND HYDRODYNAMIC FLOWS WITH FIELDS OF RESONATORS AND PERIODIC STRUCTURES

The hydrodynamic equations of inviscid compressible fluid are converted to a form suitable for development of self-consistent theory of interaction of hydrodynamic flows with resonators and periodic structures by analogy with the theory of microwave electronics devices with crossed electric and magnetic fields. We consider excitation of the acoustic velocity fields by the sources provided by vorticity in the flow.
