Convergence Study for the Volume Integral Equation Technique as Applied to Lossy Dielectric Scattering Bodies


U. Jakobus and F. M. Landstorfer

Institut fur Hochfrequenztechnik, University of Stuttgart

The volume integral equation approach in connection with cubical cells and pulse-shaped basis functions is widely employed to deal with dielectric scattering bodies. In this paper, a convergence study is conducted showing that the required cells size for modelling lossy dielectrics strongly depends on the conductivity and not only on the permittivity, as this is frequently assumed.
