STATES CHRONICLE – Is invisibility a reality? Recent research into the field of electromagnetics yielded amazing new results thanks to a team of scientists working alongside with British industry.
Electromagnetic Waves and Invisibility
In the attempt to create the coveted technology of invisibility, scientists have developed a new material. Researchers referred to the material as a nanocomposite medium. They also stated that seven distinct layers constitute the material and that each of the layers has different electric properties.
The material is thin enough to be applied as a coat to objects. Scientists demonstrated its invisibility granting options by coating a curved surface and by then examining it with an electromagnetic viewer.
Electromagnetic waves will scatter when they encounter any object in their path when moving along a flat surface. When the waves scatter, the electromagnetic signal gets disrupted. Electromagnetic viewers display the disruption and so, the object is detected.
When beset by electromagnetic waves, the material greatly limited their scatter. The electromagnetic viewer was looking right at a curved surface but it was only seeing a flat surface instead.
Scientist admitted that the material was designed with some minor inspiration from The Invisibility Cloak from the Harry Potter series by J.K. Rowling. Both the cloak and their material is based on the field of transformation optics.
Previous versions of the material proved to be less effective as they could only grant non-detection against electromagnetic waves on a single frequency. Further research, however, successfully increased the material’s range.
Along with maximizing the electromagnetic frequency range to its full spectrum, the research team would also like to be able to turn the coating into a form of fabric. Considering how fast the team has accrued its progress with the design in the past year, the world might be getting electromagnetic Cloaks of Invisibility very soon.
Non-detection and invisibility against human optics is still currently based on high-level camouflage. Current technological attempts to perfectly obscure objects from the naked eye are ineffective either due to their lack of mobility or their extremely high power consumption. Specialists believe that the technology is getting there, however.
Although, there is almost no chance cloaking will ever not be military grade hardware, what would you do if you had your very own Cloak of Invisibility?
