Directional control of light by a nano-optical Yagi–Uda antenna
作者： Terukazu Kosako , Yutaka Kadoya , Holger F. Hofmann
关键词:
摘要: A Yagi–Uda directional antenna — the work horse of radiofrequency communications for more than 60 years has now been demonstrated at visible wavelengths. An array appropriately tuned nanoparticles replicate reflecting and directing elements original design. Directional control radiation from nano-optical was experimentally shown.
