A dengue virus detection sensor has been analyzed by using two metallic layers of Ag in a photonic crystal. A blood sample is inserted between two metallic layers of Ag material in the proposed structure. In the simulation, the defect layer is a function of refractive index including plasma, platelets and hemoglobin in the patient for the detection of dengue virus. Based on the transfer matrix method, the transmittance spectra of 1D photonic crystal exhibit resonant peak within the photonic bandgap, which depends on parameter such as plasma, platelets and hemoglobin in blood, thickness of defect layer and angle of incidence. The proposed sensor gives maximum sensitivity of 1182 nm/RIU, figure of merit (FOM) of 2617/RIU and quality factor of 2228. The sensor improves the sensitivity when the thickness of the defect layer and metal layer increases with incidence angle.
