Abstract
We develop formulations for finite element computation of exterior aco ustics problems. A prominent feature of the formulations is the lack o f integration over the unbounded domain, simplifying the task of discr etization and potentially leading to numerous additional benefits. The se formulations provide a suitable basis for hybrid asymptotic-numeric al methods in scattering, non-reflecting boundary conditions and infin ite elements. (C) 1997 by John Wiley & Sons, Ltd.
