Abstract

The reflection and refraction of quasi-P(qP) wave below a transition isotropic layer sandwiched between two monoclinic media have studied. Due to incident of qP-wave at the interface of monoclinic lower half space and isotropic transition layer of thickness H, it will give rise to reflected qP, qSV, qSH-wave in the lower monoclinic half space and reflected P-wave and SV-wave at the isotropic transition layer of thickness H. As there is mother interface between transition layer and monoclinic upper-half space extended up to infinity, these two refracted P and SV-wave will incident at the interface with angle and 64 respectively. These two waves will produce reflected P and SV-wave in the transition layer and refracted qP, qSV and qSH-wave in the upper half-space of monoclinic medium in both the cases. This problem has been solved to obtain the reflection and refraction coefficients for all the waves generated using boundary conditions and the balance in energy flux normal to the boundary. Absolute numerical values of all the reflection and refraction coefficients have been obtained for a particular set up of material constants for isotropic and monoclinic media for different values of thickness of transition layer.

Reflection and Refraction of Quasi-P Wave Due to a Sandwich Isotropic Layer Between Two Monoclinic Half-Spaces

San Diego, California

The reflection and refraction of quasi-P(qP) wave below a transition isotropic layer sandwiched between two monoclinic media have studied. Due to incident of qP-wave at the interface of monoclinic lower half space and isotropic transition layer of thickness H, it will give rise to reflected qP, qSV, qSH-wave in the lower monoclinic half space and reflected P-wave and SV-wave at the isotropic transition layer of thickness H. As there is mother interface between transition layer and monoclinic upper-half space extended up to infinity, these two refracted P and SV-wave will incident at the interface with angle and 64 respectively. These two waves will produce reflected P and SV-wave in the transition layer and refracted qP, qSV and qSH-wave in the upper half-space of monoclinic medium in both the cases. This problem has been solved to obtain the reflection and refraction coefficients for all the waves generated using boundary conditions and the balance in energy flux normal to the boundary. Absolute numerical values of all the reflection and refraction coefficients have been obtained for a particular set up of material constants for isotropic and monoclinic media for different values of thickness of transition layer.
