Electromagnetic scattering of conducting bodies of revolution coated with chiral material

In this paper, the method of moment for bodies of revolution (BOR-MoM) is developed to analyze electromagnetic scattering from conducting bodies of revolution coated with chiral material. The Poggio-Miller-Chang-Harrington-Wu (PMCHW) integral equation is formulated using the surface equivalence principle, the boundary condition and Bohren´s decomposition scheme, which is applied to split a chiral media into two equivalent homogeneous media. The usage of the axisymmetric property of the bodies of revolution can convert an original problem into a series problem with small-scale matrix equations, each of which is a Fourier mode of the method of moment for bodies of revolution; selecting suitable basis functions can reduce a three-dimensional problem to a two-dimensional one. Finally, numerical results demonstrate that the developed method of moment for bodies of revolution is valid and can greatly reduce the computational complexity.
