Watching outside while under a carpet cloak of invisibility.

We demonstrate in this work a unique approach for watching outside while hiding in a carpet cloaking based on transformation optics. Unlike conventional carpet cloaking, which screens all the incident electromagnetic waves, we break the cloak and allow incident light get into the carpet. Hence outside information is detected inside the cloak. To recover the invisible cloaking, complementary tec...

Optical Cloak of Invisibility

We present the design and analysis of an optical cloak of invisibility with non-magnetic metamaterials. The general recipe for the implementation of such a device is provided. The cloaking performance is illustrated with finite-element simulations. ©2007 Optical Society of America OCIS codes: (230.3990) Microstructure devices; (160.4760) Optical properties; (999.9999) Meta-materials

Frontotemporal dementia: a peek under its invisibility cloak

Frontotemporal dementia is a group of neurodegenerative diseases that eat away at our core being. Like its comrade, Alzheimer’s disease, ageing is its best friend. Patients and families tell tales of behavioural changes that sometimes encroach on the incredible: “Mummy threw her faeces at me this morning, doc”. Language can also be lost. Words like “dog”, “eyes”, and “thing” are retained, where...

Invisibility cloak without singularity

An elliptical invisible cloak is proposed using a coordinate transformation in the ellipticalcylindrical coordinate system, which crushes the cloaked object to a line segment instead of a point. The elliptical cloak is reduced to a nearly-circular cloak if the elliptical focus becomes very small. The advantage of the proposed invisibility cloak is that none of the parameters is singular and the...

Electrostatic Field Invisibility Cloak.

The invisibility cloak has been drawing much attention due to its new concept for manipulating many physical fields, from oscillating wave fields (electromagnetic, acoustic and elastic) to static magnetic fields, dc electric fields, and diffusive fields. Here, an electrostatic field invisibility cloak has been theoretically investigated and experimentally demonstrated to perfectly hide two dime...
