This paper examines the accuracy, the time and memory consumption of the Finite Array Domain Decomposition Method (FA-DDM) applied for a large and complex low-profile metasurface-based antenna, with High-Performance Computing (HPC) for parallel processing. A validation step is performed as the technique is used for non-identical unit cells in the lattice array. Three canonical and simple structures are simulated for validation: the half-wave dipole, the half-wave dipole over a Perfect Electric Conductor (PEC) and the half-wave flat dipole over a mushroom-like Artificial Magnetic Conductor (AMC). To conclude, a large antenna system (9 x 19 cells) with high complexity is proposed to investigate the performance of the FA-DDM.
