Abstract

This paper presents work using the effective area-function approach to inverse problems in the scattering of elastic and electromagnetic waves. The emphasis in this paper is on the technique of inventing experimental elastic wave scattering data to obtain size and shape information. The procedure of elastic wave data acquisition and some results of the inversion technique are described for a small (- 1000 μm) ellipsoidal cavity. The inversion is demonstrated for 1 < ka - 4 were k is the elastic wave number and a is the effective radius of the scatterer. The scatterers are embedded in the interior of a Ti-alloy sphere.
