"Design and Measurement of Plasmonic Refractive Index Sensor Based on Resonance System with Two Rings, Two Cavities and Two Plasmonic Waveguides"

In this research, we will seek to design and numerically evaluate a refractive index nano-sensor based on the resonant system with metal insulating waveguide (MIM) that forms wide range of wavelengths. To proposed sensor structure, use two cavities rings different dimensions plasmonic waveguides. After designing examine wavelengths resonators by finite difference method time domain, because directly obtains Maxwell equations proper separation in space domains Tells us how coordinates structure achieve desired result. We also draw all diagrams using MATLAB software.
