In this paper, an efficient numerical technique is presented for analyzing the reflection and transmission characteristics of planar finite frequency selective surfaces (FSS) structures with multilayered dielectric substrate. For ideal infinite size FSS structures, only one single unit cell is of interest with the help of Floquet's theorem and periodic Green's functions. However, for FSS structures...
In this paper, an efficient numerical approach is proposed for analyzing the scattering from PEC objects above a lossy half space over wide angular and frequency band. One of the principal tools for the analysis of scattering from targets located in half-space is the method of moments (MoM) and the half-space multilevel fast multipole algorithm (MLFMA). Since the surface current and the scattered...
A full-wave analysis for the transmission characteristic of finite planar frequency selective surface (FSS) is presented using the method of moment (MoM) with the layered medium Green's functions. A fast numerical approach, the multilevel UV method, is employed to speed up the MoM solution. Finally, numerical results show the good performance of the approach, and its accuracy is verified by the agreement...
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...
