Transmission characteristics of cylindrical dipole infinite array and finite array

Finite periodic array is applied in real situation. But, generally, assumed that periodic structure is arranged infinitely, approximate electromagnetic characteristics can be obtained efficiently. Therefore, comparison and analysis of cylindrical infinite array and cylindrical finite array are required. In this paper, scattering characteristics of cylindrical infinite periodic array are obtained efficiently using cylindrical Floquet harmonics. Also, cylindrical finite periodic array is analyzed using method of moments (MoM) with thin wire approximation because periodic structures which are composed of strip with narrow width are analyzed. Transmission characteristics of each case are obtained and compared.
