Researchers Li Yi Hsu, Thomas Lepetit, and Boubacar Kante have successfully been able to create an ultra thin "dielectric metasurface cloak." It is composed of multitude of ceramic cylinders embedded into a layer of Teflon. The coating is able to mask objects from visible light and radio wavelengths, just like an invisibility cloak and the military is very aware of this. This new cloak is very well functioned by either absorbing or even directing electromagnetic waves away from an object which makes the object effectively "invisible." First, Kante told the Army Times, the new material his team had just discovered rather uses ceramics than metal particles which makes the material easier and cheaper to manufacture. Then, having the method of using ceramics and Teflon helps to allow the cloak to be more effective with coating layers that are as thin as millimeters. Kayla Matola, a research analyst with the Homeland Defense and Security Information Analysis Center (HDIAC), told the Army Times that this new cloaking technology is "basically what the military is looking for."
