Abstract :
This paper investigates the potential advantages of wavelet analysis for large scale problems in EM scattering. A biorthogonal wavelet-based method of moments (MoM) is used in analyzing 2D EM scattering from a conducting structure. Numerical examples show that wavelet-based MoM is especially suitable for the analysis of large problems in the sense that the sparseness of the resulting matrices becomes more apparent with increase of the electrical size of scatterers
