Near-zone and domain decomposition based preconditioning methods for the solution of surface integral equations

More about the book

In this thesis, different approaches are presented to accelerate the solution of electromagnetic surface integral equations. A novel near-zone preconditioner is introduced which is based on a full factorization of the strongest near-couplings. The second major contribution is the development of a domain decomposition method employing a new transmission condition derived from the near-zone matrix. The excellent performance of the proposed methods is demonstrated using a variety of numerical examples.
