The acoustic properties of ultrasound and the interaction of biomaterial and cavitation are analyzed. The relation between ultrasonic parameters and sonication is indicated. Our research revealed that different sonication aims must well match with different acoustic properties for optimizing the sonication technology. Based on the theory of wave superposition,a method for enhancement of ultrasonic intensity in wide dimension is introduced. A large scale powerful polyhedral acoustic field is built according to the research above. The rationality and effectiveness of the method are demonstrated through examination.
