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.
