Abstract

A FE-ABC (finite-element absorbing boundary condition) solution of the scattering by arbitrary 3-D structures is considered. The computational domain is discretized using edge-based tetrahedral elements. The specifics of the FE-ABC implementation are discussed. Some results are presented in order to demonstrate that remarkably accurate solutions can be obtained by enforcing the ABC a small fraction of a wavelength from the scatterer.<>
