Standard computational methods are unable to cope with wave phenomena at short wave lengths due to resolutions required to control dispersion and pollution errors, leading to prohibitive computational demands. Dispersion analysis provides a useful tool in both characterizing the performance of conventional methods and designing improved techniques. Since computation naturally separates the scales of a problem according to the mesh size, multiscale considerations provide a useful framework for viewing these difficulties and developing methods to counter them.
