Transformation rules for weak-anisotropy parameters

Ivan Psencik


Weak-anisotropy (WA) parameters turn out to be a useful way of parameterization of anisotropic media. They represent a generalization of the so-called Thomsen's parameters, which were designed for the parameterization of VTI anisotropy, to anisotropic media of arbitrary symmetry, strength and orientation. In this paper, we present some useful transformation rules for the WA parameters.
