Scattering from inhomogeneous anisotropic bodies with 3-D linear embedding via Green´s operators

We describe the application of the linear embedding via Green´s operator (LEGO) technique to the solution of scattering problems that involve objects with anisotropic electromagnetic properties. Thanks to this approach, the usage of volume integral equations is restricted to the calculation of the scattering operators of a small number of LEGO sub-domains. Since the scattering operators are surface operators, they constitute a means to reduce the computational burden. Further reduction is accomplished by applying the eigencurrent expansion method. We elaborate on the overall procedure by discussing a fewnumerical examples.
