Bridging surface plasmon polaritons and the digital world

(Science China Press) Although the concept of digital coding metamaterial has been proposed to link the digital world and physical world, it is still challenging to manipulate the digital signals in confined electromagnetic waves in deep-subwavelength scale. Scientists in China and Singapore reported a breakthrough on digital spoof surface plasmon polariton (SSPP) metamaterial to achieve the combination of tightly confined SSPP waves and digital coding and modulation technologies, which opens a ...
