中文摘要：

提出一种基于金属-介质-金属阵列结构折射率传感器.在可见光及近红外光区域内,由于表面等离子效应,入射波在特定频率时可以通过一个无缝的金,在80 nm厚的金膜上可以得到近100%的透射率.仿真结果表明传感器对周围液体的折射率变化也很敏感,这些发现可以得出一个新的、简化的替代方法,使传感器更加小型化.

英文摘要：

A refractive index sensor based on a metal-insulator-metal array structure has been proposed. In both the visible and near-infrared spectrum regions,the incident wave can transmit through a seamless gold film near a specifically designed frequency due to the excited surface plasmon resonance. A nearly 100% transmission through an 80 nm-thickness Au film can be archived. The simulation results show that it is also sensitive to the refractive index change surrounding the sensor. These findings could open a new and simplified alternative approach to make sensor more miniature.
