Array Analysis by Iterative Localised Solutions with Improved Convergence

The method of moments (MoM) is well-suited to radiation and scattering analysis of array structures. Domain decomposition strategies for array analysis, where only successive localised solutions are required to converge to the global solution, can yield high computational efficiency. Recently, such an iterative scheme has been proposed, which is denoted the direct coupling technique (DCT). In this paper, an extension to the DCT scheme is discussed, which is shown to improve its convergence. The scheme is suitable for large-scale parallelisation.
