Description

We propose a surface plasmon resonance (SPR) waveguide sensor based on the Kretschmann configuration in the THz region. First, the sensor structure is reduced to a three-layer model, and the reflectance is estimated using the Fresnel equation. The angle of incidence of the waveguide is determined to be 45°, where the reflectance of the three-layer model becomes minimum. Next, we calculate the SPR response of the waveguide sensor using the finite-difference time-domain (FDTD) method. It is shown that the absorption peak of the SPR occurs at a specific frequency. In addition, we investigate the SPR response with respect to temperature changes. The possibility of detecting water temperature is shown with high sensitivity.
