Hybridization of the finite element method and the shooting-and-bouncing ray method for scattering and radiation from large and complex targets

Many low-frequency and high-frequency techniques exist for the solution of scattering and radiation problems. In this thesis, a hybrid method combining the finite-element method (FEM) and the shooting-and-bouncing-ray (SBR) method is introduced for scattering and radiation problems from large and complex targets with small cavities or microstrip patch antennas. By combining the two methods, the advantages of each method are retained, while the disadvantages of each method are avoided. Specifically, the speed and efficiency of the SBR method are retained for the analysis of large targets, while the accuracy of the FEM is retained for the analysis of the cavities and patch antennas.
