Electromagnetic scattering properties of cylindrical frequency selective surface

In this paper, the electromagnetic scattering properties of Curved Frequency Selective Surface conformal to a cylinder surface is investigated. Four unit models are used to realize required reflection and transfer characteristics in a wide band range. Simulation shows far field radiation directivity pattern and RCS diagram of cylindrical FSS. The feature influence factors by the structure unit, the curvature of the cylindrical FSS and the dielectric-slab parameters (the thickness of the plate and the dielectric constant)are discussed.
