The model is miniaturized and the effect of the operation on total acoustic pressure and directivity index is analysed using COMSOL Multiphysics�. Effect of two different acoustic head geometries is studied. AC voltage is applied to piezoelectric actuator present in the model. Effect of changing frequency is studied. Depending on the results obtained, it was concluded that the miniaturized sonar emitter model is more suitable for cell disruption for cell organelle extraction rather than in cancer cell ablation. And also, the model with tapered acoustic head geometry showed better results. � 2018 IEEE.Book chapter
