Sixth-order finite difference scheme for the Helmholtz equation with inhomogeneous Robin boundary condition
Abstract In this paper, a class of sixth-order finite difference schemes for the Helmholtz equation with inhomogeneous Robin boundary condition is derived. This scheme is based on the sixth-order approximation for the Robin boundary condition by using the Helmholtz equation and the Taylor expansion,...
