SELF-DUAL INTEGRAL EQUATION FOR SCATTERING ANALYSIS FROM BODIES OF REVOLUTION WITH MULTIPLE IMPEDANCE BOUNDARY CONDITIONS

|In this paper, electromagnetic scattering from multi-impedance body of revolutions (BORs) is formulated using self-dual integral equations (SDIEs) and is solved numerically by the method of moments using BOR basis functions. Using the axial symmetry advantage of BORs, a 3D problem is converted to a 2D one, and a signi(cid:12)cant reduction in unknowns is obtained. This in turn leads to an increase in the speed of scattering problem solving. Numerical results show that monostatic and bistatic RCS calculation with the proposed method is about 85 and 18 times faster than the commercial software, respectively.
