Fast Inhomogeneous Plane Wave Algorithm for Analysis of Composite Bodies of Revolution

Abstract

Abstract-A fast inhomogeneous plane wave algorithm is developed for the electromagnetic scattering problem from the composite bodies of revolution (BOR). Poggio-Miller-Chang-Harrington-Wu (PMCHW) approach is used for the homogeneous dielectric objects, while the electric field integral equation (EFIE) is used for the perfect electric conducting objects. The aggregation and disaggregation factors can be expressed analytically by using the Weyl identity. Compared with the traditional method of moments (MoM), both the memory requirement and CPU time, are reduced for large-scale composite BOR problems. Numerical results are given to demonstrate the validity and the efficiency of the proposed method.

The Effect of the Dimensions of the Body on the Radar Cross Section (RCS)

“…The matter of Electromagnetic (EM) Scattering and Radiation from bodies have been studied by many researchers. One of the most efficient techniques to handle the treatment problem of scattering is the Surface Integral Equation (SIE) which was developed to analyze the properties of the scattering of these objects when it own describe the Body of Revolution (BOR), body of revolution can be defined as the body that is produced by a curved rotation called a curved around a particular axis called the axis of symmetry (Rui et al, 2010). This body is a three-dimensional target and is transformed from a three-dimensional problem into a number of binary issues using the advantage of symmetry as well as reducing the time and storage of the desired computer to resolve this problem (Rao et al, 2017).…”
