Energy flux streamlines vs the alternatives for the visualization of energy coupling inside and outside the surface of an ensonified spherical acoustic lens: Preliminary results.

Abstract

Energy flux streamlines are compared with alternative presentations of the energy flux vector field to visualize energy coupling inside and outside the surface of an insonified spherical acoustic lens. The emphasis is on the energy flux streamline as a natural bridge between necessarily approximate ray solutions and full-fledged wave solutions. The present work is the wave solution for the experimental work performed by Kendez C. Parker and Cleon E. Dean also being presented at this meeting that primarily used ray methods in its theoretical analysis; thus a comparison between energy flux representations and ray analysis results is made. Difficulties in the interpretation of the energy flux streamline representation due to the spherical geometry of the scatterer are noted.
