Reflection and Transmission of a Three-Dimensional Plane qP Wave through a Layered Fluid Medium between Two Distinct Triclinic Half-Spaces

This paper discusses reflection and transmission phenomena of a three-dimensional (3D) plane quasi-P (qP) wave incident at a triclinic half-space superimposed by a fluid layer underneath another distinct triclinic half-space. The closed-form expressions are obtained for reflection and transmission coefficients of corresponding reflected and transmitted waves. These reflection and transmission coefficients are computed numerically and shown graphically for fixed values of relevant parameters. Certain problems have been discussed as special cases to the present problem. The findings of the current study can be used to analyze problems with similar geometry in different elastic mediums, such as monoclinic, transversely isotropic, and isotropic.
