Propagation and Absorption of Finite-Amplitude Sound in Biomedical Tissues*

Thursday, May 13, 1993 10:00 a.m. Ping-Wah Li Department of Physics The University of Texas at Austin A theoretical investigation of the propagation and absorption of finite-amplitude acoustic waves in media with thermoviscous and multiple relaxation mechanisms will be presented. A nonlinear wave equation, called the generalized Burgers equation, is derived for this purpose. Analytic…
