0107704 High-low frequency technique combined with computational complex electromagnetic scattering [J]. NIE Xiao-chun // Chinese Journal of Microwaves.-2000,16 (5) .- 480 ~ 484,521 (K) In this paper, the high frequency approximation method combined with the low frequency numerical method Method to Calculate the Scattering of Two-Dimensional Slotted Electrical Large Target. Firstly, the target scattering field is decomposed according to the principle of equivalence. Iterative physical optics method and boundary element method are used to calculate slot-filled electric targets and slot scattering respectively. And the problem of aperture coupling is dealt with using generalized network principle and reciprocity theorem. The data results show that this method is more accurate and efficient. Participation 5
