Abstract
In this paper, we propose a plasmonic nanosensor based on a metal/insulator/metal plasmonic waveguide with a rectangular resonator. The proposed nanosensor can be used for mechanical strain and thermal stress sensing. We investigated the plasmonic resonance modes based on a standing wave model in the rectangular resonator. In addition, the plasmonic resonances of the rectangular resonator were numerically investigated using the finite-difference time-domain method. The bonding and anti-bonding modes of the plasmonic resonator can be expressed using the mechanical model of coupled harmonic oscillators.
