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 less than 1 25. The spatial index variation is realized by etching holes of various sizes in.

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. 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.

A carpet cloak for visible light. We report an invisibility carpet cloak device which is capable of making an object undetectable by visible light. 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. Invisibility carpet cloak can hide objects from visible light the carpet cloak design that transforms a mirror with p into miniature invisibility carpet cloak hides more than its small quasiconformal mapping based carpet cloaks a 2d microwave.

The carpet cloak. Gharghi m gladden c zentgraf t et al. 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. To date broadband carpet cloaking based on metasurfaces has not been achieved and operation has been limited to discrete wavelengths.
