Absorbing Boundary Conditions for Convex Object-Conformable Boundaries

Omar M. Ramahi, Member, IEEE

Page 1141.

Abstract:

Absorbing boundary conditions (ABC's) are developed that can be applied on object-conformable outer boundaries. The new ABC's are based on the local enforcement of the N th order Bayliss-Turkel boundary conditions where a scattering center is defined for each outer boundary node. A demonstration of the effectiveness of the new construction is provided by considering representative numerical experiments using the finite-elements method. Results show that the new ABC's provide accuracy that compares very favorably with the method of moments solution.
