Scientists from Tomsk Polytechnic University jointly with Russian colleagues and researchers from Technical University of Denmark the first time have experimentally proved the existence of a two-dimensional (2D) curved flux of plasmonic quasiparticles, a plasmonic hook. A flat 2D hook is smaller than a 3D hook and possesses new properties, due to them, the researchers consider it as the most promising transmitter in high-speed microoptical circuits. The research findings are published in Applied Physics Letters journal.
