Periodic and Pulsed Sawtooth Wave Propagation through Nonlinear and Inhomogeneous Media

Wednesday, October 28, 1992 4:00 p.m. Professor Oleg V. Rudenko Department of Physics Moscow University, Russia A theoretical model for nonlinear geometrical acoustics is developed by simpli­fying the general and parabolic nonlinear wave equations on the basis of high­ frequency approximations. Physical phenomena associated with high acoustic intensities, such as nonlinear refraction and self-defocusing, and…
