SEEING THROUGH WALLS. "This is achieved by using a remote device that transforms the scattered light outside a virtual boundary into that of the object chosen for the illusion, regardless of the profile of the incident wave. This type of illusion device also enables people to see through walls." https://lnkd.in/eyBstN6 View in LinkedIn

SHIFTED-POSITION CLOAK. "We propose a composite optical transformation to design an illusion device which can move the image of a target from one place to another place. Enclosed by such an illusion device, an arbitrary object located at one place appears to be at another place virtually." By using metamaterials, to make an illusion device (2010). https://lnkd.in/euGhtCU View in LinkedIn

UNIMAGINABLE. "It is pretty amazing to think that one could simply bolt a block of material onto a wall and suddenly be able to see through it." https://lnkd.in/eckFFcR View in LinkedIn

FIVE YEARS. "This is just one example of the amazing things we can do with the concept of transformation optics, the same concept that produced the ideas behind electromagnetic cloaking. Only five or so years ago, we would have not even imagined that this could be done." https://lnkd.in/eckFFcR View in LinkedIn

ILLUSIONS. "Directionally hiding objects and creating illusions above a carpet-like device by reflection holography." https://lnkd.in/e7eyJgs View in LinkedIn

"THE DEVICE is fabricated through recording a reflection hologram of objects and is used to produce a time-reversed signal to compensate for the information of the objects and further to create light field of another object so as to realize both functions of hiding the objects and creating illusions, respectively." https://lnkd.in/e7eyJgs View in LinkedIn

MACRO APP. "The carpet-like device can work for macroscopic objects at visible wavelength as the distance between objects and device is at decimeter scale. Our carpet-like device to realizing invisibility and creating illusions may provide a robust way for crucial applications of magic camouflaging and anti-detection etc." https://lnkd.in/e7eyJgs View in LinkedIn

TIME-REVERSAL. "So far, time-reversal principle has been widely exploited to produce phase-conjugation signals for not only imaging beyond the diffraction limit, focusing light into a scattering medium, but also concealing objects and creating illusions." https://lnkd.in/e7eyJgs View in LinkedIn

HOLOGRAPHY. "We employ reflection holography to produce reflection time-reversal light to realize hiding objects and creating illusions above a carpet-like device through reflection observation." https://lnkd.in/e7eyJgs View in LinkedIn

PRACTICAL. "The carpet-like devices can work for macroscopic objects (at centimeter scale) at visible wavelength when the distance between the objects and the carpet-like devices is at the decimeter scale. In addition, the devices are made of commercially available all-dielectric materials." https://lnkd.in/e7eyJgs View in LinkedIn
