Abstract: In this thesis, electromagnetic scattering problems of large and complex objects are studied. We have considered the large-scale electromagnetic problems of three types of scatterers, i.e., perfectly electric conducting objects, dielectric objects, and composite conducting and dielectric objects. The integral equation method has been used to characterize the scattering problems of these three types of scatterers and the MoM is applied to convert the integral equations into a matrix equation. Then by using the AIM, the matrix equation can be solved efficiently on a personal computer. In addition to the AIM, several preconditioning techniques have also been used to further accelerate the solution of the scattering problems. These preconditioners are constructed by using the near-zone matrix generated by the AIM. By using these preconditioners, the number of iterations and the overall solution time have been effectively reduced.
