一种测量水中硝酸盐的金属光学天线的研究与设计

RESEARCH AND DESIGN OF A METAL OPTICAL ANTENNA FOR MEASURING NITRATE IN WATER

1985年,Wessle提出光学天线的概念。U.C.Fischer等人在1988年首次实验验证了Wessle的理论。由于金属微纳结构具有局域表面等离子体效应,光学天线对局域场具有增强和调制的功能,因此金属光学天线在光谱增强方面具有重要的作用。本文通过研究水环境中金属光学天线的红外特性,设计了一种用于测量水中硝酸盐的金属光学天线。

The concept of optical antenna proposed by Wessle in 1985[1].U.C.Fischer tested the theory of Wessle for the first time in 1988.Because metal micro nanostructures have local surface plasma effects,optical antenna can enhance and modulate the local field.Therefore,the metal optical antenna plays an important role in spectral enhancement.In this paper,a metal optical antenna for measuring nitrate in water is designed by studying the infrared characteristics of the metal optical antenna in the water environment.
