No full textA Combination of Integral Equation Method and FD/TLM Method for Efficient Solution of EMC Problems
No full textIn this contribution we deal with the development of a novel hybrid Finite Difference-Integral Equation method (FDIE) in which the efficient Integral Equation method (I.E.) is combined with the very flexible Finite Difference method (FDTD) / the Transmission Line Matrix (TLM) method. With that the FDIE method has got the high flexibility of a space discretizing method and the efficiency of the Integral Equation method for the analysis of large homogeneous regions. So the FDIE method is applicable for the analysis of EMC problems. It makes possible the efficient computation of complex structures which are coupled by their far fields. In a typical EMC problem the method is applicated to the modeling of the radiation from apertures in metallic enclosures which is a. The numerical results of the FDIE method are compared with results obtained by the TLM method and with data from literature, showing a very good agreemen
Analytical modelling of 3D-dielectric corners for E.M. simulators
No full textIn this work we present a novel model of the dielectric cubic corner, that is suitable for inclusion in a standard E.M. simulator. The model starts from a consideration of the equivalent current densities on the cube facets. It proceeds by employing a classical multipole expansion of the Green's function at the corner and introduces the novel principle of Simultaneous Transverse Resonance (S.T.R.) to determine the order of singularity. The theory is validated by the use of a standard FEM-based simulator, yielding information about the near field and the radiation pattern of the corne
