Design of Narrow-Band Absorber Based on Symmetric Silicon Grating and Research on Its Sensing Performance
In this paper, using the surface plasmon and Fabry–Pérot (FP) cavity, the design of a symmetric silicon grating absorber is proposed. The time-domain finite difference method is used for simulation calculations. The basic unit structure is a dielectric grating composed of silicon dioxide, metal and...
