title: Plasmon-induced transparency in coupled triangle-rod arrays.
abstract: We demonstrate polarization-dependent plasmon-induced transparency in coupled triangle-rod arrays. The observed phenomenon is the result of the destructive interference between the bright and dark resonators in this coupled system, which is verified through the numerical simulations using the finite-difference time-domain (FDTD) method. By precisely controlling the structural parameters of the coupled triangle-rod system, the plasmon-induced transparency can be effectively manipulated. This plasmonically coupled nanostructure could be potentially useful for designing and developing artificial plasmonic molecules and metamaterials with desired functions, which may further find promising applications in biosensing, nanoparticle trapping and optical filters.
