Abstract :
A diakoptic surface integral-equation formulation is applied to 2-D transversal magnetic (TM) scattering problems. The diakoptic formulation is based on the equivalence (Huygens´) principle. The aim of the diakoptic formulation is to reduce the CPU time needed for the electromagnetic analysis and the memory needed for the data storage without compromising the final results. The proposed diakoptic formulation is illustrated on two examples of 2-D TM scatterers. The calculated radar cross-section (RCS), CPU time, and storage requirements are compared to those of the classic method of moments (MoM).
