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…
