基于纳米线的表面等离子激元传感器研究

In this paper, we mainly studied the sensing perfermance of metal nanowire sensor based on surface plasmon ploarizations. We used power detection method to discuss influence on sensor's sensitivity by radius of nanowire, incident light waveleng and the sample environment refractive index. In the next part of the paper, we proposed metal nanowire with dielectric nanowire sensor and researched on its sensening perfermance.
