“Coloration is essential,” as pop artist Roy Lichtenstein famously stated, however the significance of coloration extends far past artwork. From the creation of Prussian blue—the primary artificial pigment—to quantum dots in fashionable show know-how, colours and their creation have at all times mirrored technological progress.
Researchers at ETH Zurich’s Laboratory for Nanometallurgy have developed a brand new fabrication technique for non-primitive metasurfaces, by which the colours of those metasurfaces symbolize and visualize light-matter interactions. The paper is revealed within the journal Superior Optical Supplies.
To showcase the capabilities of those metasurfaces, the researchers recreated Lichtenstein’s iconic “Sinking Solar” on the nanoscale. This copy illustrates how particular resonant states—or, in easier phrases, colours—may be engineered by cautious manipulation of geometry and supplies. Consequently, these metasurfaces are ideally fitted to encoding info in ways in which stay visually imperceptible, providing a sturdy deterrent in opposition to counterfeiting.
