Pseudospectral Time-Domain Modeling of Nondestructive Ultrasonic Fields

Nielsen, S. A.; Lynova, J. P.; Kristensen, W. D.

Acoustical Imaging — 2000, pp. 183-188

In conclusion, a major limitation of the finite-difference scheme is numerical dispersion. A pseudospectral method is proposed for the accurate solution of spatial derivatives in nonperiodic domains. The method is based on a Chebyshev collocation scheme. The method requires much fewer grid points
