Resumen

Understanding wave propagation, reflection, and transmission 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 triclinic 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.
