We present static and dynamic computations of the apparent properties for stacks of horizontal isotropic layers (VTI symmetry).

The effective stiffness tensors of such media are given by the Backus theory for statics in the limit of zero thicknesses of the constituent layers. We used COMSOL Multiphysics to verify the theoretical static bounds for these effective stiffnesses.
