摘要：

A compression algorithm is presented for discrete representations of boundary-integral operators. The algorithm relies on an expansion of the unknown surface currents in a numerically determined basis of functions that are simultaneously localized to small regions on a large target while also satisfying global boundary conditions. It is shown that the resulting local-global solution (LOGOS) modes provide efficient approximations of the impedance matrix at low to moderate frequencies. (c) 2005 Wiley Periodicals, Inc.
