Popis: This contribution presents a domain-decomposition preconditioner that achieves higher rates of convergence than comparable methods and is yet simple to implement. Its numerical properties are illustrated by examining the eigenvalue distribution of the preconditioned finite element matrix. The practical usefulness of the proposed method is demonstrated by reference to a large-scale antenna array.
