With the development of science, The magic of invisibility is getting closer to us. Let’s take a look at these new technologies: Professor Chen Hongsheng’s research group at the International Academy of Electromagnetic Sciences at Zhejiang University collaborated with other research teams to create bio-invisible devices in the visible light band using glass.
As long as the little fish’s body enters the “invisibility cloak”, it will literally disappear from sight. Professor Chen said that although it is still far from practical application, human invisibility cloak is still expected to become a reality. The paper “Research on the Interaction Mechanism of Electromagnetic Waves and Invisibility Cloaks” written by Chen Hongsheng in collaboration with the Massachusetts Institute of Technology was published in the top academic journal of physics “Physical Review Letters”.
The paper explains the physical mechanism of the invisibility cloak for the first time and proposes a theoretical framework for quantitative analysis of the invisibility effect. This achievement plays an important guiding role in the design of the invisibility cloak. The well-known science and technology website “Global Science News Network”, which is famous for reporting the latest international scientific research results, reported the research results in detail under the title “Scientists explain the physical mechanism behind the invisibility cloak” and conducted an exclusive interview with Chen Hongsheng. The principle allows light to flow around the stone like a stream.
According to the Russian “Informing” news network on November 8, Singaporean scientists are about to develop a unique “invisibility hat”.
Researchers at Nanyang Technological University, led by scientist Zhang Peier, have been developing an “invisible” hat for three years. Experts have successfully created a system that can hide objects from human sight. However, this invention can currently only “hide” some smaller items or small animals.
Scientists say that so far, the mirror effect can make part of an object “invisible”, but the other part of the object is still visible as a whole. Scientists will conduct further research on how to hide all objects.
According to reports, this invention could be used in multiple fields, especially in the defense industry. American researchers recently used these invisible principles to design a specific device for microphotonic integrated devices, which helps develop photonic chips that are smaller, faster, and more energy-efficient than silicon-based chips.
