In this paper, a new simple refractive index (RI) sensor based on plasmonic nanostructure D-shape fiber is proposed. In this structure, surface plasmon resonances are sensitive to the surrounding medium on the flat side of the D-shape fiber. In the proposed sensor, the sensitivity of 1025nm/RIU is obtained. The significance of the proposed sensor lies with its compact in size, robust and simple in structure, and high value of sensitivity. In addition, an important property of the designed structure is that the excitation of surface plasmon resonances in this type of fiber is simple. The proposed structure can be applicable to the identification of different bio-molecules or chemical materials.
