| Résumé: | In this paper, a plasmonic sensor is proposed based on a metal-insulator-metal waveguide coupled with a double-triangle resonator. The sensing structure is numerically and theoretically investigated using the two-dimensional finite difference time domain (FDTD) method. The results show the presence of a linear relationship between the materials refractive indices and the sensor's wavelength resonances. The proposed structure revealed a high sensitivity value, reaching the maximum value for mode 1 Smode1 = 1374 nm/RIU, and for mode 2 Smode2 = 2365 nm/RIU. The proposed sensor can be classified as a high-performance nano-sensor that can be used to identify different materials |
