The performance of the OSRC method for concentric penetrable circular cylinder

Abstract

In this paper we consider the scattering of a wave by concentric penetrable circular cylinder to examine the performance of higher order SRCs up to the L-4 operator in two dimensions. We assume that in the rectangular Cartesian axes, (x,y,z), the z axis coincides with the axis of a cylinder and an incident wave propagates in a direction perpendicular to the cylinder. All the field quantities are then independent of z. (c) 2006 American Institute of Physics.
