Abstract

This paper presents a novel radiation boundary condition (RBC) with the spectral integral method (SIM) to truncate the computational domain in the finiteโ€element method (FEM). Because of the spectral accuracy of the SIM, the sampling density on the radiation boundary requires less than four points per wavelength to achieve a high accuracy (1%). As a result, the introduction of the SIM as an RBC actually can decrease the total number of unknowns in the system equation. Numerical results illustrate the usefulness of this novel RBC for both homogeneous and inhomogeneous objects. ยฉ 2007 Wiley Periodicals, Inc.

The scaled boundary รฟnite element method, alias the consistent inรฟnitesimal รฟnite element cell method, is developed starting from the di usion equation. Only the boundary of the medium is discretized with surface รฟnite elements yielding a reduction of the spatial dimension by one. No fundamental sol
