Control of Nonlinear Standing Waves in Acoustic Resonators
Original language description
Though there are a number of methods which enable to control acoustic fields in resonators, this paper is focused on possibilities that offer the use of amplitude-modulated primary waves. This method makes possible to control energy transfer among harmonics and thus to form the acoustic field inside resonators. Better efficiency is achieved by a combination of the standard methods of influencing acoustic fields such as the method of acoustic resonance macrosonic synthesis, induced dispersion, selected absorption etc. The presented method of acoustic field control enables to suppress the generation of higher harmonics and thus suppress the nonlinear saturation effect. At the same time it offers new possibilities for excitation of nonlinear standing acoustic waves which are based on piezoelectric transducers.
