The world's first battery-powered invisibility cloak gives you instant power
According to media reports, if people can have super powers, I am afraid many people want to stealth. The truth is that people don't have super powers, but they don't have to be disappointed. Researchers at the University of Texas at Austin are working on a battery-powered invisibility cloak that they claim can improve stealth. The research work starts from the existing invisibility cloak that uses the surface of the element to deflect and refract light. The main purpose of the design is to add batteries to enhance the signal and ensure that the invisibility cloak is not visible under any lighting conditions. However, this battery-powered invisibility cloak is currently only a theory, but the research team hopes to build an achievable model as soon as possible.
Associate Professor Andrea Alù, the lead member of the research project, and his team recently proposed a design for the existing invisibility cloak that uses battery power to amplify the stealth spectrum to a wider frequency range. Fundamentally, it increases the invisibility by adding an external energy, and makes the invisible effect perform better under various conditions.
The invisibility cloak is still a crazy and futuristic design. With the help of a high-tech material called the meta surface, it minimizes the scattering of light, thus allowing the hidden objects to reach Invisible effect. These materials can work in certain situations, but not all conditions, and objects hidden under bright white light may still be seen. The research team report described that expanding the width of the invisibility cloak would be achieved using a non-resistive metasurface material, and they would use an external power source to improve the performance of the metasurface material.
Alù explained: “We have demonstrated that the cloak can increase the broadband band, and the discovery has pushed the invisibility cloak technology beyond its current limitations.†This active cloak uses batteries, circuits and amplifiers to reduce light and radio signals at wider frequencies. Scattering within the range.
