Abstract

The treatment of field and scattering problems by means of method of moments (MoM) produces a system of linear equations which has to be solved. For large-scale structures the numerical effort for an LU decomposition of the system matrix becomes unacceptable. Iterative solvers can be an alternative but they often require a sophisticated preconditioner. A simple but powerful preconditioner can be derived from the physical meaning of the blocks in the impedance matrix and is applicable to a wide range of EMC problems. Using iterative methods can also be of significant advantage in another class of problems
