A Carpet Cloak For Visible Light

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.

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

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. 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 less than 1 25. A carpet cloak for visible light. 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.

Gharghi m gladden c zentgraf t et al. Undetectable by visible light. 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 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.
