Abstract

ABSTRACT

In this paper, we consider wave propagation in a periodically layered medium with orthorhombic symmetry. The weak‐contrast approximation is utilized to derive the low‐frequency dispersion in effective properties for P, S1 and S2 waves. We show that the dispersion term for all effective properties is controlled by the second‐order contrasts in elastic properties from the layers. We also compute the sensitivity matrices for second‐ and fourth‐order coefficients from eigenvalues of frequency‐dependent system matrix associated with kinematic parameters for individual wave modes.
