We are concerned with an integral method applied to the solution of the Helmholtz equation where the linear system is solved using an iterative method. We need to perform matrix-vector products whose time and memory requirements increase as a function of the wavenumber . Many methods have been devel

## Abstract A dual boundary integral equation (BIE) formulation is presented for the analysis of general 3βD electrostatic problems, especially those involving thin structures. This dual BIE formulation uses a linear combination of the conventional BIE and hypersingular BIE on the entire boundary o
A domain decomposition method (DDM) is presented for the solution of the timeharmonic electromagnetic scattering problem by inhomogeneous 3-D objects. The computational domain is partitioned into concentric subdomains on the interfaces of which Robin-type transmission conditions are prescribed. On t
