image: This shows thermal radiation modes emitted by spin-optical metamaterial based on inversion asymmetric kagome lattice. The illuminated color spirals symbolize the photon helicity-split due to optical Rashba effect. False-colored electric field distribution near the metasurface obtained by numerical simulation. The design of photonic metasurface symmetries via geometric gradient of the optical antenna patterns provides a route to control light-matter interaction at the nanoscale. This image relates to a paper that appeared in the May 10, 2013, issue of Science, published by AAAS. The paper, by Nir Shitrit at Technion-Israel Institute of Technology in Haifa, Israel, and colleagues was titled, "Spin-Optical Metamaterial Route to Spin-Controlled Photonics." view more
