摘要:

In an isotropic, noncentrosymmetric (chiral) elastic solid, the displacement fielduhas to be supplemented by the independent microrotation field φ. Since such a medium is mirror asymmetric or chiral, six different wavenumbers are possible: of these, two represent longitudinal fields, and the remaining four are circularly polarized. This paper is concerned with the scattering of elastic plane waves by a planar interface between an achiral elastic solid half‐space and a chiral elastic solid half‐space.
