Is cloaking tech possible?

The good news is that the new research confirms that invisibility is indeed possible. These facts combine to mean that while we can make something like an antennae or military radar invisible to radio waves, it is nearly impossible to cloak something the size of Harry Potter from the naked eye.

What are the future possibilities of cloaking device?

Digital coding metasurfaces simultaneously manipulate both electromagnetic and acoustic waves for advanced cloaking or signaling devices. 3-bit digital coding metasurfaces could be used in masking detection by radar and sonar systems.

Who invented cloaking technology?

According to Worlds of the Federation, the Romulans developed the first cloaking technology and traded it to the Klingons in exchange for warp drive technology – an exchange which both sides bitterly regretted in the following years, when they became deadly enemies.

Is there a real-life cloaking device?

While their device only masked an object from one wavelength of microwave light, it does provide more information that will help us to consider if a real-life cloaking device is possible. This cloaking device was made from a group of concentric circles with a cylinder in the middle, where an object could be placed.

Can we make a cloak that works on more than one wavelength?

However, there’s still a lot of work to be done before a working cloak is developed for more than one wavelength of the visible spectrum, much less the sort seen in science-fiction movies. At the moment, making a device that works on all wavelengths of visible light is beyond scientists’ capabilities.

Is it possible to create a color cloaking device?

It may be possible in the future to create some sort of phasing cloaking device, in which each color of the spectrum of visible light is cloaked for a fraction of a second. If accomplished at sufficient speed, an object would likely appear translucent, though not quite invisible.

How does microwave light re-inform a cloaking device?

The Duke team used metamaterials to make their cloaking device have gradually varying refractive indices — from 1 on the outside of the device, decreasing to zero in the center. The result is that microwave light subtly bends around the device and is able to reform on the other side, albeit with some detectable distortion.
