The AVO and AVAz contain valuable information about the elastic properties of a subsurface media. However, the conventional approaches are based on plane-wave theory, which cannot explain observations near the acoustic critical reflection and far offset null reflection at Rayleigh angle. In this contribution, we show our algorithm to understand the acoustic reflectivity of liquid-solid boundary...

The purpose of this research is to study the reflection transverse waves in the GreenLindsay theory for kind of smart materials under initial stress and relaxation times effect. It is found that, for two dimensional model of thermo-piezoelectric material, there exists four waves namely, quasi-transverse wave (QS-mode), quasi-longitudinal wave (QP-mode), thermal wave ( -mode), and potential elec...
