Acoustic and elastic modeling using bases for bandlimited functions | CU Experts

Overview

In this paper we describe a novel algorithm for solving acoustic and elastic wave equations. The algorithm utilizes prolate spheroidal wavefunctions for representing bandlimited functions. Key features of the method are high accuracy, elimination of numerical dispersion, and close to optimal sampling rates. Numerical results in two and three dimensions are presented which demonstrate the accuracy of the method and its ability to handle complex media such as the SEG salt model.
