Abstract-This paper presents a new hybrid finite-difference frequency domain -mode-matching method (FDFD-MM) for the analysis of electromagnetic wave scattering from configuration of metallic or dielectric cylindrical posts with arbitrary cross-section. In our approach each scatterer is treated as an effective circular cylinder represented by impedance matrix defined in its local coordinate system. In order to obtain the scattering parameters of arbitrary configuration of objects in global coordinate system an analytical iterative scattering procedure (ISP) is applied. This work is an extension of our previously published results, where our consideration were limited to two dimensional (2D) problems with TM excitation. In this paper, we extended our analysis to two-and-a-half dimensional (2.5D) problems. The accuracy of the proposed method is presented and discussed. To verify our approach some numerical examples are presented. The obtained results are compared with the results published in literature and the ones obtained from own measurements and commercial software.

“…The resonance frequencies of the investigated structure are determined in a function of the number of eigenfunctions M and the mesh density W. All the results are collected in Tables 1 and 2. The results are compared with analytical solution [9] and with commercial software QuickWave. It can be seen that for considered structure M ¼ 7 and N ¼ 30 Â 90 is enough to obtain accuracy better than 0.003% in comparison to the analytical solutions.…”

A new iterative T-matrix algorithm combined with iterative scattering process (ISP) has proposed for dealing with the scattering characteristics of cylindrical objects. The relationship between incident and transition filed can evolve from the cylindrical harmonics of one cylinder. With the iterative scattered field among cylinders each time considered as the incident field of iterative process next time, total iterative scattering matrix can be reached. With iterative curves each time analyzed, it is verified that the process of iterative among the cylinders is equivalent to the coupling process among cylinders. To test the veracity of the proposed theory, scattering of four cylinders with arbitrary radius has been calculated with both iterative T-matrix algorithm and the method of moments (MoM). The results compared show that the iterative T-matrix algorithm and MoM agree well.
