Abstract
In this work, the problem of reducing the scattering from conductive cylinders is reformulated by considering a matching problem with radial transmission lines. A unique compact closed-form solution for the surface impedance loads Z s (m,kb) above a cylindrical grounded dielectric substrate is found without any approximation as a function of the harmonic index m (scattering mode to suppress) and of the frequency regime kb (product of wavenumber k and radius b of the cloaked system). Possible implementations with a microstrip-line based metasurface are discussed and presented.
