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

<div>A THz refractive index sensing experiment setup integrating a SPR grating with THz TDS in a reflection measurement mode. The measurement should be carried out in a low-humidity environment and at room temperature to avoid strong THz attenuation due to moisture.</div>
