Anti-mirror optical illusion could increase LED luminosity and laser power: the researchers showed that illusion devices with elliptic cylindrical PECs can be used in place of both real cylindrical PECs. Once again, the two illusion devices look like one PEC. As the scientists explained, this effect occurs because the two illusion devices are close enough together so that their virtual illusion spaces overlap. Inside this shared region, both illusion devices form a single PEC image.
“The two PECs on both sides of the perfect lens follow the image-forming principle so that each of them is overlapped with the virtual image of another,” Chen explained to PhysOrg.com. “The anti-mirror effect stems from the evanescent wave amplification of the perfect lens.”
