Hybrid plasmonic nanoprisms in the form of gold (Au)-dielectric- silver (Ag) sandwich structures have been designed and simulated using Finite-difference time-domain (FDTD) simulation technique. Simulations results show two dipole resonant peaks for the hybrid sandwich structure. Also, a strong wavelength dependence of the plasmonic resonance peaks on the edge length and the thickness of gold and silver layers. The increase in edge length and thicknesses were found red shift to the plasmonic peak of the nanostructures. Furthermore, the resonant wavelengths and relative strength of the two dipole plasmonic peaks are demonstrated to be tunable.
