Abstract

In an isotropic, noncentrosymmetric elastic solid, the displacement field u has to be supplemented by the independent microrotation field. In this mirror-asymmetric (or chiral) medium, six different wave numbers are possible: Of these, two represent longitudinal fields, and the remaining four are (circularly) handed. This paper is concerned with the scattering of elastic waves by a chiral sphere, and the effect of the chiral parameter on its scattering response.
