Abstract :
Presents the development of a new class of absorbing boundary conditions (ABCs) that can be applied on non-circular convex mesh termination boundaries. The new ABCs are based on the exact application of BT operators using local scattering centers. This work demonstrates the application to scattering problems in 2D space and in the frequency domain. however these ABCs are applicable directly to scattering problems in 3D space and to time domain problems.
