AIM solution to electromagnetic scattering using parametric geometry

This paper presents the adaptive integral method (AIM) utilized to solve electromagnetic scattering problems of an arbitrarily shaped conducting body with parametric geometry. The combined field integral equation is used to characterize the scattering problems of a closed conducting body whose surfaces are modeled using curvilinear patches. The formulated integral equations are then discretized and converted to a matrix equation using the method of moments. The resultant matrix equation is then solved by an iterative solver and the AIM is employed to accelerate the matrix-vector multiplication. Numerical results are presented to demonstrate the efficiency of the technique.
