| Abstract: | We have studied the propagation of longitudinal strain solitons in waveguides made of polystyrene and plexiglas (polymethyl
methacrylate) and long enough to provide noticeable changes in the wave shape and amplitude. The decay rate for nonlinear
waves in these materials is estimated from the experimental data. An anomalously weak attenuation of strain solitons in polymers
featuring a high dissipation of linear waves is discovered for the first time. |
