We are getting closer to making an invisibility cloak that will enable aircraft to vanish into thin air, and this latest technology is one advancement. Researchers at University of Texas at Austin have developed an active invisibility cloak that enables more effective shielding of an object at a wider variety of light frequencies. Continue reading for a video and more information.
Mashable reports that “during experimentation, scientists made a cylindrical rod invisible, and determined this with the aid of machines and systems tracking microwave or radio frequencies, which are outside of what humans can see in the visible light spectrum. Light frequencies are all in the electromagnetic spectrum, where visible light wavelengths are a very small part of the spectrum that is visible to the human eye.”
