If young Harry and friends had not cruised around Hogwarts unseen, hidden by an “invisibility cloak,” much of the hype surrounding metamaterials might itself never have seen the light of day.

An invisibility cloak works by bending light around a central ... This control is supplied by optical metamaterials, which are (usually) periodic nanostructured materials, where the periodic ...

It might change in the future with more advanced passive metamaterials, but for now active designs are the way forward. Research into active invisibility cloaks is currently being carried out by ...

and hybrid metamaterials," says Mitri. Applications of the technology, to name only a few, include: invisibility cloaks to hide objects from radar and sonar detection, sub-wavelength focusing for ...

The quest to build a working “invisibility cloak” generally focuses on the use of metamaterials – artificially engineered materials with a negative refractive index that have already been ...

Metamaterials are designed to have unique ... Examples include super-lenses to view objects at the molecular scale; invisibility cloaks, which refract all visible light; and perfect wave ...

The combination of 3D and 4D printing technologies with EMMs holds great promise for the future, driving innovation and opening up new avenues for research and development in multiple disciplines.

Metamaterials first captured the public imagination in 2006, when John Pendry of Imperial College published two papers showing how to create a Harry Potter-style invisibility cloak using the ...

Researchers advance 3D and 4D printed electromagnetic metamaterials (EMMs) - enabling the production of next-generation ...

The concept of “digital metamaterials” – a simple way of designing metamaterials with bizarre optical properties that could hasten the development of devices such as invisibility cloaks and ...
