    Abstract

    In this work, we demonstrate experimentally with bistatic microwave measurements the effective cloaking of a long conducting (metallic) cylinder. The device that enables this cloaking effect is – unlike most known cloaks – a very simple structure composed of two conventional dielectric materials. Both materials are isotropic and homogeneous and have the relative permittivity larger than unity. The device design is carried out with an analytical model and is validated numerically. The cloaking effect of the realized cloak is characterized by measuring the bistatic scattering patterns of uncloaked and cloaked objects in free space and then comparing these with each other.
