A comparative study of plasmon-polariton resonance excited by graphene and different metals in the terahertz range is proposed. The optimum structure is prism/(sample/pomusTa(2)O(5))(7)/sample/plasmon layer/ substrate. The variation of the proposed sensor performance as a function of the thickness of the plasmon layer, thickness of the porous layer, porosity of the porous layer, refractive index of the first layer, thickness of the first layer, and the incident angle with changing the refractive index from 1 to 1.1 using Ag, Al, Au, Cu, and graphene are studied. Under optimum conditions, the proposed sensor has very high performance (sensitivity = 5.5 THz/RIU, figure of merit = 341 RIU-1, and quality factor = 210). The proposed structure can be used in refractive index gas sensors.
