The Simulation of a Surface Plasmon Resonance Metallic Grating for Maximizing THz Sensitivity in Refractive Index Sensor Application

<div>Reflectance of an Au/PDMS grating with Λ = 190 <i>μ</i>m, <i>H</i> = 95 <i>μ</i>m, FF = 0.5, and <i>t</i><sub><i>m</i></sub> = 100 nm at the incident angle of 10° as a function of frequency. An inset is the |<i>H</i><sub><i>y</i></sub>| field distribution along one unit of the grating structure.</div>
