Abstract:

Results were obtained on the reflection of waves from rough boundaries. Novel features are the calculation of second moments of the scattered field and the relation of the results to those of Twersky. In addition the effective viscosity tensor of a periodic suspension and the effective elasticity tensor of a periodic composite were calculated for all concentrations up to close packing. The acoustoelastic effect has also been analyzere. Various new results on inverse scattering have been obtained in two and three dimensions. Keywords Nonlinear waves Heterogeneous media Reciprocal theorems and Effective parameters.
