Metamaterial cloaking is the usage of metamaterials in an invisibility cloak. This is accomplished by manipulating the paths traversed by light through a novel optical material. Metamaterials direct and control the propagation and transmission of specified parts of the light spectrum and demonstrate the potential to render an object seemingly ...
This idea, commonly known as the Invisibility cloak, has stimulated much recent work in the field of metamaterials. [23] In 2009 he and Stefan Maier received a large grant from the Leverhulme Trust to develop the ideas of perfect lens and invisibility cloak in the optical range of light. [24]

The first electromagnetic cloaking device was produced in 2006, using gradient-index metamaterials.This has led to the burgeoning field of transformation optics (and now transformation acoustics), where the propagation of waves is precisely manipulated by controlling the behaviour of the material through which the light (sound) is travelling.
If you ever hoped an invisibility cloak was a real thing, you will be happy to know that one now exists. Unfortunately, it will only work on something incredibly small, specifically microscopic.
The history of metamaterials begins with artificial dielectrics in microwave ... and is considered one the leaders in the science of creating an invisibility cloak ...
Ukraine has reportedly developed a real-life "invisibility cloak" that can hide soldiers from thermal cameras thanks to its unique properties that block heat signature radiation.The images show ...
