The idea for the invisible blanket emerged from experiments conducted by MIT researchers. The researchers used a transformation design process to create an invisible cloak of Carbon nanotubes that conduct heat. This infinitely thin surface appears to be another silver rooftop. The canopy conceals the view of anyone who is not under it. However, the sun filters through the golden underside to reveal the city.
Quantum cloak
A quantum cover is a physical device which allows an object to hide from an observer. A conformal mapping is a process in which the mass parameters and states of a particle are converted to isotropic states using an external force. This is known as a quantum cloak. This force is known as the electric force.
A quantum cloak can be a useful tool for military use. Through its unique combination light-bending nanotechnology fabric, it can hide an object. This type of cloak is being tested on marines and soldiers to provide cover against sniper strikes.
Transform design method creates invisible cloak
The transformation design method allows you to create an invisibility blanket. The transformation method considers the physical properties of a material to be the basis of the design. The radial index and azimuthal components determine the cloak's characteristics. These components can change from zero - one at the cloak's inner and outer borders.
The authors created a cloak using ultrasonic waves to hide the material's physical properties. The number of parameters needed to achieve invisibleness was reduced by the authors. This preserves the invisible effect and preserves effective refractive.
Carbon nanotubes conduct heat
Carbon nanotubes are extremely thin sheets of carbon that can conduct heat very efficiently. Scientists studying the nanotubes found they can reach temperatures above 2,800 kelvins, without burning the carbon. This is more than twice what is generated by an average flame.
These nanotubes are available as single-wall, double wall, or multi-wall options. You can visualize the single-wall version by wrapping a 1-atom-thick graphite sheet around a cylinder. The double-wall version has a gap between conduction and valance band.
