| Abstract | ||
| In this paper we investigate the electromagnetic scattering by dielectric bodies of revolution (DBOR) with attached wires in the present of common region (junction) between wire and Body of Revolution (BOR) surface, where the composite and irregular body is formed. A surface integral equation (SIE) technique is developed to analyze the scattering properties. Two vector integral equations (IEs) via Maxwell's equation, Greens theorem, and the boundary conditions are used. The formulations are generated by the standard electric field integral equation (EFIE) and PMCHWT, and numerically evaluated by the method of moment (MoM) technique with Galerkin's approach. The numerical results are validated for DBOR and compared with that of other researchers, while for DBOR-wire-junction compared with conductor bodies of revolution (CBOR)-wire-junction, which satisfied by comparing with experimental data. Furthermore, the addition of attached wires significantly alters the constant CBOR and DBOR cross-section, and the effect of changing dielectric constant (εr ) will be disparate among different values on the radar cross section (RCS). | ||
