After years of science fiction media, the public revered wands and spells as products of the far future. Chu Junhao, a physicist from the Chinese Academy of Sciences, assisted in making a specific product come true. In regards to the new, light-manipulating invisibility cloak, he states, “Whether in real life or in the world of nature and animals there is a lot of 'invisibility', and this is not magic, it is a scientific means”. 


The Chinese Invisibility Cloak is more formally known as chimera metamaterial. Researchers observed the chameleon-like nature of this material. To be invisible to the naked eye, researchers concocted a process to ensure concealment. The steps include the overlapping of the metamaterial. Each layer contributes to the complete invisibility this cloak provides. The first layer reflects microwaves (electromagnetic radiation). The following layer gives the illusion of transparency. The final layer conceals body heat underneath the cloak using cooling properties.


Although this invention can assist the day-to-day lives of ordinary citizens through observations of animals or searching for lost people, ethical problems begin to arise. Invisible technology does not have a foundation for its rules and regulations yet. Therefore, crimes similar to spying and stalking disturb citizens. 


Specifically due to the concealment of body heat, this will give the Chinese military an advantage. For instance, large equipment may be concealed. This may range from artillery to tanks. 


The scientists are both regarded and criticized for the future of this invisibility cloak. Though military personnel can use it to their advantage, citizens are worried about their privacy. With both of these profound consequences, the government will need to set ground rules for the usage of this dangerous, yet fascinating invention.
