A concurrent periodic/non-periodic technique for large phased arrays

In this paper, a brief overview of a proposed simple concurrent periodic/nonperiodic analysis scheme, the decompose-solve-recompose (DSR) technique, is presented for the modeling of planar large phased array (LPA) systems. The resulting 2D spatial DSR technique, known as the hybrid edge-periodic DSR technique, requires the decomposition of a large planar array into an outer edge "ring" array and a central periodic array block. Since computational cost is a very important criterion in the analysis and design of an LPA, a cost function analysis example is presented.
