✦ Synopsis

In recent years, the generalized multipole technique GMT and other fictitious source methods ha¨e been widely used to sol¨e electromagnetic scattering problems. Ne¨ertheless, these methods ha¨e been shown to be ¨ery sensiti¨e to the source locations, and often produce ill-conditioned matrix systems. The current approach suggests a kind of synthesized directi¨e expansion to reduce the dependence on the source locations, the condition number of the impedance matrix, and the number of unknowns.

The generalized multipole technique is a new method for solving electromagnetic boundary value problems. A set of basis functions is used which may be thought of as equivalent sources which are displaced from the boundary of the scatterer. Actually any discrete set of solutions to Maxwell's equation

In this letter, a new method for reconstructing the bound of impenetrable two-dimensional objects is presented. From a set of measurements in the near-or far-field region, we calculate the coefficients of multipolar equi¨alent sources located inside the unknown object. Thus, the shape of the object

## Abstract This paper presents a fast formulation of the hybrid boundary node method (Hybrid BNM) for solving problems governed by Laplace's equation in 3D. The preconditioned GMRES is employed for solving the resulting system of equations. At each iteration step of the GMRES, the matrix–vector mu
