摘要：

In this paper, we have analyzed and simulated the behavior of a nanoscale refractive index sensor in two-dimensional plasmonic waveguide with nanodisk resonator, using the numerical method of finite difference time domain (FDTD). The analytic and simulation results demonstrate the linear correlation between the resonance wavelengths of the nanodisk of the sensor and the refractive index of the material under sensing. The resolution of the sensor depends on the wavelength resolution of the detection system. This sensor can be exploited for identification of various materials, especially as a useful biosensor, by proper design. (C) 2013 Elsevier B.V. All rights reserved.
