In this paper, the properties of cylindrical high permittivity dielectric particles are studied. A design for broadband reduction of the scattering signature of metallic objects is proposed by implementing simplified ground-plane cloaking schemes. The devices are functional in the presence of a ground plane as well as in free space ranging from 4 GHz to 10 GHz. The required dielectric map for the cloak is achieved by means of manipulating the dimensions of the periodically distributed dielectric cylinders embedded in a host medium with a permittivity close to one. The scattering reduction effects are verified through simulation results. The proposed all dielectric cloaks are advantageous over other schemes due to their non-dispersive nature, the broad bandwidth, the low loss, and the ease of fabrication.
