Abstract :
The paper presents a fast EFIE MoM analysis of structures with fine details, non-uniform meshes, formed by surfaces and wires. The developed hierarchical preconditioner is efficiently integrated with a MoM iterative fast solver to analyse electrically large objects. The numerical results show a strong reduction of the number of iterations with a very low memory overhead.
