“Coloration is essential,” as pop artist Roy Lichtenstein famously stated, however the significance of shade extends far past artwork. From the creation of Prussian blue—the primary artificial pigment—to quantum dots in fashionable show expertise, colours and their creation have all the time mirrored technological progress.
Researchers at ETH Zurich’s Laboratory for Nanometallurgy have developed a brand new fabrication methodology 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 replica illustrates how particular resonant states—or, in easier phrases, colours—could be engineered by way of cautious manipulation of geometry and supplies. Because of this, these metasurfaces are ideally suited to encoding info in ways in which stay visually imperceptible, providing a strong deterrent towards counterfeiting.
