Seismic Reflection Analysis in Functionally Graded Anisotropic Medium with Imperfect Boundary

Ponente(s): Akanksha Srivastava Srivastava, Dr. Federico J. Sabina

Understanding wave propagation and seismic reflection analysis in anisotropic media with imperfect boundaries is essential for advancing research in both geophysical exploration and the design of engineered materials. Motivated by advances in reflection seismology, my recent research focuses on amplitude analysis in a functionally graded anisotropic medium, with particular emphasis on the reflection of three-dimensional plane wave at imperfect boundary. Seismic amplitude-versus-angle (AVA) methods, which relate reflection amplitudes to the angle of incidence, provide a robust framework that can be useful in the exploration of subsurface geological materials and in advancing our comprehension of the Earth’s interior structure. In this context, analytical expressions for amplitude ratios as functions of incident angle are derived using the generalized Snell’s law, along with corresponding expressions for energy ratios and slowness surfaces. Graphical demonstrations further illustrate how anisotropy, functional grading, and boundary conditions influence amplitude ratios, energy partitioning, and wavefront geometry.
