Abstract wereportaninvisibilitycarpetcloakdevice whichiscapableofmakinganobject undetectable by visible light.

Carpet cloak visible.

The cloak redirects and bends the light such that this distortion is countered the mirror appears to be flat and the object is invisible. Ultrathin metasurfaces pave an encouraging way for invisibility carpet cloaks on account of their excellent electromagnetic wavefront manipulation. We report an invisibility carpet cloak device which is capable of making an object undetectable by visible light. Andrews in scotland who was not involved in either study says the future of optical legerdemain lies not in hiding things but in revealing them.

The cloak is designed using quasi conformal mapping and is fabricated in a silicon nitride waveguide on a specially developed nanoporous silicon oxide substrate with a very low refractive index n less than 1 25. Ulf leonhardt a physicist at the university of st. Here the cloak sits on top of a bump in a mirror. We report an invisibility carpet cloak device which is capable of making an object undetectable by visible light.

To date broadband carpet cloaking based on metasurfaces has not been achieved and operation has been limited to discrete wavelengths. The cloak is designed using quasi conformal mapping and is fabricated in a silicon nitride waveguide on a specially developed nanoporous silicon oxide substrate with a very low refractive index n 1 25. An object can be hidden under the mirror the carpet yet without cloak the bump would still be seen as a distortion in the mirror reflection. However the current metasurface based carpet cloaks operate at only one wavelength and are limited by their narrow bandwidth.

Here we propose and numerically demonstrate a novel metasurface design for broadband carpet cloaking with linear polarization at visible wavelengths from 650 nm to 800 nm. The cloak is designed using quasi conformal mapping and is fabricated in a silicon nitride waveguide on a specially developed nanoporous silicon oxide substrate with a very low refractive index n 1 25.
