Abstract

Propagation of elastic surface waves in anisotropic media is considered in this study. An analytical technique is proposed to study the scattering of surface waves at the interface between two anisotropic quarter-spaces. The Green's function technique is used to derive a system of equations which can determine the scattering coefficients at the interface. A numerical study is carried out and the trade-offs between the material anisotropy and inhomogeneity are studied.

이방성 재료에서의 표면파 진행과 산란에 대한 연구를 수행하였다. 두 개의 이방성 4분 무한 영역의 계면에서의 표면파 산란거동을 해석하기 위한 이론을 제안하였다. Green 함수법을 이용하여 계면에서의 표면파 산란계수를 결정하기 위한 방정식을 유도하였다. 수치계산을 수행하였으며 이방성과 비균질성이 산란 거동에 미치는 영향을 비교하였다.
