Abstract :
A new plasmonic-like waveguide structure is proposed for integrated terahertz refractive index sensing. The surface plasmon-like wave is an effective means for high sensitivity sensing in the terahertz range, but most of the reported configurations are based on free space excitation using a prism, that is not convenient for integration. In the proposed structure a dielectric waveguide is used to excite the sensor. Dispersion characteristics and the sensitivity of the structure are calculated using COMSOL full-wave simulations.
