High-order method of moments for solving bodies of revolution using asymmetric wavelet transform
For fast and accurate analysis of electromagnetic scattering problem of bodies of revolution, the high-order moment of method (MOM) is constructed based on Chebyshev polynomials so that the dimension of the impedance matrix can be reduced. To further improve the computational efficiency, the asymmetric wavelet transform technique is introduced to make the low dimension impedance matrix sparse, and the number of nonzero elements is reduced drastically by setting suitable threshold. The effectiveness of the new proposed method is validated by numerical simulation of differently shaped objects.
