The perfect cylindrical cloak requires three spatial variant material parameters, which is very difficult to realize in practice Science 312, 1780 2006. The approach of realizing the electromagnetic cloaking by concentric layered structures instead of using the metamaterial was presented Optics Express, Vol. 15, No. 18 2007. We use the concentric layered structures to realize a simplified cylindrical cloak with improved parameters and an ideal cylindrical cloak with spatially invariant axial material parameters. Numerical simulation results validate that cloaking performance is significantly improved compared with previously proposed multilayered cloak.
