Abstract

The Higher-Order Array Decomposition Method (HO-ADM) is extended to arrays with non-identical elements. This extension is achieved by appropriate manipulation of the FFT-accelerated matrix-vector product (MVP), special meshing, and by hiding a selected subset of unknowns in the iterative solution process. We demonstrate that the simulation time for a 1024-element patch array can be reduced by an order of magnitude by employing HO-ADM compared to other fast methods such as MLFMM.
