The idea for the invisible blanket emerged from experiments conducted by MIT researchers. They used a transformation design method to develop an invisibility cloak made of Carbon nanotubes, which conduct heat. The surface appears like another silver roof from the sky, and is infinitely thin. 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 cloak is a physical device that enables an object to remain hidden from the observer. In theory, a quantum cloak is generated by a conformal mapping, in which the mass parameters of a particle are transformed to isotropic states by applying an external force. This force is known by the electric force.
A quantum coat can be an effective tool for military purposes. The unique combination of light-bending nanotechnology fabric and nanotechnology fabric can conceal an object from enemy view. To provide protection against sniper attacks, this cloak has been tested by marines and soldiers.
Based on the transformation design method, invisibility cloak
The transformation design method allows you to create an invisibility blanket. The transformation method takes into account the physical properties of a material as the basis for designing. Using this method, the cloak's properties are determined by the radial and azimuthal index components. These components change from zero to one at the inner and outer boundaries of the cloak.
The physical properties a material has meant that the authors have created an invisible cloak, which uses ultrasonic waves to make it invisible. The number of parameters needed to achieve invisibleness was reduced by the authors. This preserves the invisibility effect while also preserving the effective refractive Index.
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 nearly twice the heat generated by an average fire.
These nanotubes are available in single-wall, double-wall, and multi-wall forms. You can visualize the single-wall version by wrapping a 1-atom-thick graphite sheet 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.
