Abstract

We have introduced a new method called the hybrid/sup 2/ method. It combines a local (FEM), a global (integral equation formulation/BEM) and an asymptotic method (UTD). With this method we can solve very efficiently antenna and scattering problems involving highly inhomogeneous objects and electrical large structures. The results obtained are very reliable for the near field as well as for the far field. The method is very flexible, because it is the user´s decision, whether he models an object close to the antenna by means of the exact FE/BE methods or by means of the asymptotic UTD method; thus, he can make it compromise between computation time/memory requirements and accuracy of the results for the actual problem under consideration.
