标题： Multifrequency broadband tapered plasmonic nanoantennas

摘要： 我们建议一种新型多频段宽带等离子体Yagi-Uda型纳米天线，该天线配备有锥形定向器阵列。 每个定向器可用于通过与定向器共振频率光谱匹配的纳米发射器进行天线激励，并放置在定向器近场区域。 纳米天线的多频段操作为宽带发射增强、光谱分析和传感提供了巨大的机会。 根据互易性原理，相同的锥形纳米天线结构既可以作为发射器，也可以作为接收器，因此对于创建宽带无线通信系统很有用。 显示英文摘要

摘要： We suggest a novel multifrequency broadband plasmonic Yagi-Uda-type nanoantenna equipped with an array of tapered directors. Each director can be used for the excitation of the antenna by nanoemitters matched spectrally with the director resonant frequency and placed in the director near-field region. Multifrequency op- eration of nanoantennas provides tremendous opportunities for broadband emission enhancement, spectroscopy and sensing. By the principle of reciprocity, the same tapered nanoantenna architecture can be used both as a transmitter and/or as a receiver, thus being useful for creating a broadband wireless communication system.
