Research by MIT scientists led to the idea for the invisible blanket. They used a transformation design method to develop an invisibility cloak made of Carbon nanotubes, which conduct heat. This thin, transparent surface looks like another rooftop in the sky. The canopy hides visitors from view while the city below is visible.
Quantum cloak
A quantum cover is a physical device which allows an object to hide from an observer. The theory behind a quantum veil is that it is created by conformal mapping. In this process, the mass parameters of a particles are transformed into isotropic forms by an external force. This force is called the electric force.
A quantum coat can be an effective tool for military purposes. Through its unique combination light-bending nanotechnology fabric, it can hide an object. To provide protection against sniper attacks, this cloak has been tested by marines and soldiers.
Transform design method creates invisible cloak
The transformation design method allows you to create an invisibility blanket. The transformation design method uses the material's physical properties as the basis for the design. The radial index and azimuthal components determine the cloak's characteristics. These components are shifted from zero to one at both the outer and inner borders of the cloak.
The authors created a cloak using ultrasonic waves to hide the material's physical properties. The authors reduced the number parameters to achieve invisibility. This preserves the invisible effect and preserves effective refractive.
Carbon nanotubes conduct heat
Carbon nanotubes, which are very thin carbon sheets that conduct heat extremely efficiently, are extremely thin sheets. The scientists who studied the carbon in the nanotubes found that they can reach temperatures of 2,800 kelvins without burning the carbon. This is more than twice what is generated by an average flame.
These nanotubes can be made in single-wall or double-wall configurations. The single-wall version can be visualized by wrapping a one-atom-thick sheet of graphite around a cylinder. Contrary to the single-wall version, which is simpler and has a gap among the valance & conduction bands, the double wall version is more complicated.
