Caption: Elliptically polarized dipole, pictured as two rotating opposite charges, designed to excite surface plasmons unidirectionally in a nearby metal surface. The height of the metal surface represents the simulated surface charge density. This video relates to a paper that appeared in the April 19, 2013, issue of Science, published by AAAS. The paper, by Francisco Rodríguez-Fortuño at King’s College London in London, UK, and colleagues was titled, “Near-Field Interference for the Unidirectional Excitation of Electromagnetic Guided Modes.”
