BGU Researchers Make an Optical Chip Invisible

BGU researchers have achieved a breakthrough in manipulating light to theoretically render an object, such as an optical chip, invisible.

According to the recent study Invisibility Cloaking Scheme by Evanescent Distortion on Composite Plasmonic Waveguides with Si Nano-Spacer  published in Nature Scientific Reports , the researchers conceived a new method that deflects and scatters light away from a “cloaking” chip surface so it is not detected.

An operational cloaking chip can be an extension of the basic technologies such as radar-absorbing dark paint used on stealth aircraft, local optical camouflage, surface cooling to minimize electromagnetic infrared emissions, or electromagnetic wave scattering.
