“…The co-polarization radiation patterns of Yamaguchi TTC and M/IOT Station, which was constructed in 1980, achieved the Recommendation CCIR (now ITU-R) S.465 [28]. Moreover, Yamaguchi NO.2 Earth Station satisfied not only co polarization patterns, but also cross-polarization patterns with this Recommendation by using shaped struts for the subreflector [29].…”

“…One group of these components are the structures where cylindrical posts of arbitrary shape are applied to obtain desired scattering parameters [1][2][3][4][5][6][7][8][9][10][11][12]. Generally, in the analysis of these components open and closed problems can be distinguished.…”

“…In the open problems, the near or far scattered field pattern of a set of cylindrical objects located in free space and illuminated with plane wave or Gaussian beam is the subject of interest. These structures are applied to the reduction of strut radiation of reflector antennas [1,2], novel EBG structures realized as periodical arrays [3,4] and polarizers [5,6]. In the closed problems the result of the analysis are scattering parameters of waveguide junctions or resonant frequencies of resonators loaded with cylindrical objects.…”

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.
