Abstract
This article describes the application of an absorbing boundary condition for truncating finite element meshes in the analysis of phased-array antennas. For a plane wave incident on a planar boundary at a certain specified angle, this boundary condition can be tuned to be reflectionless for all frequencies and polarizations. To demonstrate its application, this boundary condition is implemented in the dual-primal finite-element tearing and interconnecting method for simulation of large-scale phased-array antennas. A good performance is achieved in terms of accuracy and convergence of the numerical solution.
