摘要: The field scattered by truncated thin cylinders excited arbitrarily oriented and polarized elementary electromagnetic sources is analyzed means of the incomplete Hankel functions (IHFs). currents on related fields are derived solving electrical integral equations (EFIEs) point-matching method moments (MoM) using triangular basis functions. IHFs employed so to express distribution in closed analytical form, thus allowing obtain accurate numerical results. Structures having finite conductivities or formed dielectric materials modeled surface impedance boundary conditions including curvature effects. Cylindrical structures, made up carbon fibers, useful realize focusing systems reflector antennas, cylinders, suitable model plant shapes, taken into consideration for purpose identifying their scattering properties.
