Elastic wave scattering calculations and the matrix variational Pade approximant method
Abstract
The matrix variational Pade approximant and its generalization to elastic wave scattering are discussed. Predictions of the method for the scattering of a longitudinal plane wave are compared with the exact scattering from spherical voids and inclusions. Its predictions are also compared to those of the first and second Born approximations and to the standard matrix Pade approximant based on these Born approximations.
