A Decompose-Solve-Recompose (DSR) TechniqueAbstract
A novel spatial Decompose-Solve-Recompose (DSR) technique is demonstrated to be very attractive for analyzing uniform and non-uniform large phased array (LPA) antennas, because it can accurately account for array edge effects. A simple concurrent periodic/ non-periodic analysis scheme, similar to that utilized in the Progressive Numerical Method (PNM), is presented for the modeling of planar large phased array antennas. 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.
