These types of waves are described in terms of two complex vectors or bivectors: the slowness bivector and the amplitude bivector.

WebbQUALITY FACTOR OF INHOMOGENEOUS PLANE WAVES 599 pic media, we compare the two expressions for Q as a function of the inhomogeneity angle. In addition, we study the anisotropic case for qP– qS waves in the symmetry plane of an orthorhombic medium. In a medium with anisotropy and attenua-tion, beyond a given degree of wave … Webb28 feb. 2011 · which restricts the value of β for any attenuating wave with a given value of Q.This implies that even for a highly attenuating inhomogeneous wave (i.e., Q-1 ≤ 0.1) the contribution of its homogeneous propagation to the total attenuation (κ < 1) may be less than five percent. However, for the restricted homogeneous propagation, i.e. δ = 0, the … pittman judge

We show how the theory of complex vectors, or bivectors as Hamilton and Gibbs called them, may be used in the study of inhomogeneous plane waves propagation in poroelastic materials.
