Ivan S. Maksymov, Arthur R. Davoyan, Yuri S. Kivshar

摘要:

我们介绍了一种设计的八木宇田等离子体纳米天线,用于提高天线增益和实现控制的角度发射的光。我们证明,锥形的天线元件允许减少天线元件之间的间距十倍,也提高了其发射方向性。我们找到了最佳的锥角,提供了最大的方向性增强和最小的端射波束宽度。

英文摘要:

We introduce a design of Yagi-Uda plasmonic nanoantennas for enhancing the antenna gain and achieving control over the angular emission of light. We demonstrate that tapering of antenna elements allows to decrease spacing between the antenna elements tenfold also enhancing its emission directivity. We find the optimal tapering angle that provides the maximum directivity enhancement and the minimum end-fire beamwidth.
