We present a feasible invisibility approach: a scattering-cancelation cloaking scheme based on the design of the scattering response of arbitrary shaped objects. We derive a generalized Hilbert transform, relating he real and imaginary part of the object susceptibility which leads to a judicious cancellation of the scatterings at the reciprocal wavevector domain. We show that such a procedure yields optical invisibility for any arbitrarily shaped object within any specified frequency bandwidth by simply employing isotropic non-magnetic dielectric materials, without the usage of loss or gain material. The validity of the design principle is verified by direct experimental observations of the spatial electric field profiles at the microwave regime, and full-wave numerical calculations of the scattering patterns. This cloaking strategy may have profound implications especially in non-invasive probing and cloaked sensor applications, where the wave penetrability into the sensor is essential together with its invisibility to minimize the field distortion. |
