Multi-Structure-Based Refractive Index Sensor and Its Application in Temperature Sensing

Multi-Structure-Based Refractive Index Sensor and Its Application in Temperature Sensing

In this paper, a new sensor structure is designed, which consists of a metal–insulator–metal (MIM) waveguide and a circular protrusion and a rectangular triangular cavity (CPRTC). The characterization of nanoscale sensors is considered using an approximate numerical method (finite element method). T...
