A Carpet Cloak Device For Visible Light

We report an invisibility carpet cloak device which is capable of making an object undetectable by visible light.

A carpet cloak device for visible light. We report an invisibility carpet cloak device which is capable of making an object undetectable by visible light. The carpet itself has the appearance of a smooth optical mirror so that the object and the bump that the object makes underneath the carpet are undetectable by visible light. Previous devices have been able to hide objects from light travelling in only one direction. We report a cloak device that makes objects undetectable by visible light.

We report an invisibility carpet cloak device which is capable of making an object undetectable by visible light. The cloak is designed using quasi conformal mapping and is fabricated in a silicon nitride waveguide on a specially developed nano porous silicon oxide substrate with a very low refractive index. The cloak described in the journal science hid an object from detection using light of wavelengths close to those that are visible to humans. The carpet cloak.

Invisibility carpet cloak can hide objects from visible light 15 june 2011 by lisa zyga when an input beam black arrow reflects off a a bump without a cloak the bump causes a perturbation. 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. It is designed using conformal mapping and is fabricated in silicon nitride waveguide on nano porous silicon oxide substrate with very low refractive index. Viewed from any other angle the object would remain visible.

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. Additionally an area ofconstanthole size surrounding the cloak device is required to provide a uniform background index. 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. A crystalline silicon wafer is electro.
