Abstract

The Higher-Order Array Decomposition Method (HO-ADM) has been extended to regular arrays with dielectric substrates. To maintain the multi-level block-Toeplitz Method of Moments (MoM) matrix structure, internal equivalent currents are introduced, ensuring an FFT-accelerated matrix-vector product (MVP). Results demonstrate a tenfold reduction in computation time and lower memory consumption compared to an existing fast method, specifically for a 400-element array of PEC cylinders embedded in a dielectric substrate.
