Physicist Organization March 26 in the latest issue of “Optics Letters” magazine, the French scientists confirmed that many of the principles of optical invisibility cloak technology able to develop the transfer object to focus on certain hot thermal stealth or a regional “hot invisibility cloak.” The scientists said that the latest technology is expect ed to better control the heat dissipation in electronic devices, outdoor led spotlights, is also expected for the aerospace and solar technology.
At present, the progress achieved in the field of invisibility cloaks are based on the transformation of the basic principles of optics, which relates to the use of metamaterials and use it to allow light to bend, outdoor led spotlights, around the propagation of light in a space rather than through the space. For this reason, the Aix-Marseille University and the French National Scientific Research Center (CRNS), a joint researcher Sebastian Guna You led the team decided to clarify whether the same method can be used for the thermal diffusion.
Guna You said: “We conducted this study the main objective is: to use the conversion of optical tools, outdoor led spotlights, the success has been achieved in the field of sound and light ‘invisible’ to control the proliferation of hot.”
Guna You explained the basic principles of the latest technology and optical cloak, but there is still a critical difference. To date, the cloak to the trajectory of the operating wave for the center, including light and sound waves, LED high bay, but the biggest difference of the thermal field of the wave field contains the physics of the phenomenon of thermal diffusion rather than wave propagation.
The Guna You said: “is not a heat wave, it just spread from high temperature to lowtemperature, outdoor led spotlights, therefore, in these two areas from a leading role in mathematics and physics is very different principle. For example, the wave energy long distance travel attenuation is small, but a very limited range of temperature diffusion.
In order to create a hot invisibility cloak, Guna You and colleagues will be converted to optical principles of physics applied to the thermal diffusion equation and found that “hotcloak of invisibility” technology can be achieved.
