A Carpet Cloak Device For Visible Light

Previous devices have been able to hide objects from light travelling in only one direction.

A carpet cloak device for visible light.

The carpet cloak. 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. We report an invisibility carpet cloak device which is capable of making an object undetectable by visible light. The spatial index variation is realized by etching holes of various sizes in.

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 nano porous silicon oxide substrate with a very low refractive index. The device fabrication process begins with the preparation of the low index substrate. 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. We report an invisibility carpet cloak device which is capable of making an object undetectable by visible light. A crystalline silicon wafer is electro. 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. 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. The cloak described in the journal science hid an object from detection using light of wavelengths close to those that are visible to humans.

Nanoletters a carpet cloak for visible light we report an invisibility carpet cloak device which is capable of making an object undetectable by visible light.
