On the connection of T matrices and integral equations

The authors describe the connection between the major numerical techniques of computational electromagnetics. These are the T-matrix methods and the surface- or volume-integral-equation methods. Both homogeneous (e.g., guidance, resonance) and inhomogeneous (e.g.. scattering) equations can be solved with these two methods. The recursive T-matrix algorithms have been applied to the electromagnetic problem of scattering from ten strips of width w and spacing d=2w.<>
