Abstract :
In this paper we propose the use of the Multilevel Domain Differentiated (MDD) model to analyze structures with fine details, non-uniform meshes, and large overall sizes. The MDD method is able to significantly improve the spectral properties of the EFIE MoM matrix for broad-band analysis, employing a multi-scale representation of the solution to deal differently with different scales. Here the method is validated against measurements on an aircraft fuselage model.
