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