Integral Equation Modeling of Radiation Problems using Mixed Mesh Element Discretizations

The mixed mesh discretization scheme has been applied to solve hybrid integral equations for electromagnetic scattering and radiation. The mixed mesh scheme makes it easier to model complex objects without significantly increasing the number of unknowns. The program from this mixed scheme algorithm has been validated using exact solutions for spherical objects. When accelerated by MLFMA, this algorithm has the potential to solve many realistic problems as demonstrated by the examples shown in this paper
