Scattering and Radiation Problem of Surface/Surface Junction Structure with Multilevel Fast Multipole Algorithm

Abstract

In this paper, a good many electric large structures are modelled as Surface/Surface structure. Using the surface/surface junction model to simulate the targets with no thickness junction plane instead of thin plane, the number of unknowns and the memory could be reduced greatly. Moreover, for the antenna problem of probes excited, using this model to simulate probes or dipoles, the uniform basis function can be used in this model and no need to introduce a special basis function to the junction. Therefore, it is more suitable for the MLFMA analysis. Numerical results obtained in this paper show the validity and the accuracy of the method.
