STRONG MODE TRANSFORMATION OF ELASTIC WAVES BY SPHERICAL SOLID OBJECT

Xin Zhang, Fu‐Gen Wu

Abstract

We investigate mode transformation between longitudinal mode and transverse mode by spherical solid object. By analyzing the scattering cross section, we find that longitudinal wave (L) transformation to transverse wave (T) is much more than transverse wave (T) transformation to longitudinal wave (L). The ratio of L → T converted waves to T → L converted waves is verified to be independent of frequency. The strongest mode transformation between transverse mode and longitudinal mode can be obtained by choosing a solid sphere with large density and low shear velocity and background with small density and high shear velocity.
