Abstract

Developments over the past several years have led to renewed study of theoretical methods for treating scattering of ultrasound by defects in elastic solids. Characteristically, many theories of scattering, until a few years ago, dealt with scalar waves and simple obstacles. Within that context two distinct regimes were apparent -- the long wave length, and the short wave or imaging regime. The treatment of vector fields in elastic solids is considered the more cumbersome, but we now have made progress -- still for idealized configurations. Specifically, the talk will deal with hypotheses on the types of problems which face us in the next generation of situations.
