Sonic excitation by means of ultrasound; an experimental illustration of acoustic radiation forces

摘要: Ultrasonic acoustic waves are known to induce a vibration of particles around an equilibrium position. However, for large amplitudes, due non-linear effects, rectified, net radiation force can occur. Experimental work is performed in which the behavior exploited generate dynamic that used dynamically excite small structure at sonic frequencies. The forces quantified experimentally inverse manner from structural displacement being excited by forces.
