Results show that the radar cross-section of the structure vanishes at some specific frequencies.

In this paper, we propose a novel approach for the analysis of shielded microstrip circuits, composed of a number of thin metallic areas with arbitrary shapes and finite conductivity, embedded in a multilayered Iossy medium. The analysis is based on the solution of an integral equation (IE) obtained by enforcing the proper boundary condition to the electric field on the metallic areas. The IE is solved by using the method of moments with entire domain basis functions, which are numerically determined by the boundary integral-resonant-mode expansion (BI-RME) method. The use of the BI-RME method allows for the efficient calculation of the basisfunctions independently on the shape of the domain, thus permitting the analysis of a wide class of circuits. Two examples demonstrate the accuracy, rapidity, and flexibility of the proposed method.

An efficient characteristic mode solver is proposed for the solution of characteristic modes (CMs) of large-scale finite periodic arrays. Firstly, the CMs of an isolated reference element are obtained using the standard characteristic mode solver. Then, by choosing the first several CMs of the isolated reference element with larger mode significance (MS) to construct the entire domain basis functions, the proposed method can dramatically reduce the matrix dimension of the resultant generalized eigenvalue problem governed by the entire array structure, thereby significantly reduce the computational time and memory requirement.

This paper presents an efficient method for analyzing the metasurface of varying clement sizes or rotate angles. In this method, the characteristic modes (CMs) for metasurface element can he obtained by solving a generalized eigenvalue problem (GEP) based on the mixed potential integral equation (MPIE). Then, by choosing the first several CMs of the isolated reference element with larger mode significance (MS) to construct the entire domain basis functions, the induced current of the metasurface structure can be expanded using the set of entire domain basis functions. By truncating the order of the entire domain basis functions, this method can significantly reduce the number of unknowns and greatly reduce the computational time and memory requirement.

A new numerical method is proposed for the analysis of metallic scatterers which can take care of the singular integrals arising in the Method of Moments (MoM) solution for determining the current distribution on the metallic scatterers. The method involves Monte Carlo Integration (MCI) technique in solving the Electric Field Integral Eq. (EFIE). The unknown current distribution is represented in terms of the entiredomain polynomial basis, functions. It is found that the proposed method is capable of removing the singularity problem arising in the MoM solution of the EFIE very easily (aid efficiently. (c) 2008 Wiley Periodicals, Inc.
