LARGE-ANGLE PARABOLIC EQUATION METHODS

James T. Kirby

Abstract


Large-angle parabolic equation methods for the propagation of surface water waves are discussed. The methods described here are limited to forms which are solvable by the Crank-Nicolson method, but are successful in opening the allowed range of propagation directions to ~ 50° with respect to normal incidence.
