Fast analysis of electromagnetic scattering from body of revolution using high-order basis functions

Electromagnetic scattering by conducting body of revolution (BOR) is formulated in terms of the electric field integral equation combined with high-order basis function based on curved-wire segment. Owing to the rotational symmetry property of BOR, the currents are represented using high-order basis functions along the generating arc and Fourier series expansion for the periodic azimuthal variation. The method of moment for BOR (BORMoM) is applied to the linear system solved by the direct solver. The parallelisation is carried out in the high-order BORMoM to further reduce the computation time. Numerical results are presented to demonstrate the accuracy and efficiency of the proposed method.
