Abstract- In this article, an array of metal nanostructures including disk and ring is investigated using finite difference time domain (FDTD) method. It is shown that ring-disk nano structures array supports two plasmonic resonance modes. Our results indicate that symmetry breaking in this structure leading to the Fano resonance. Also the LSPR sensitivity of different resonances are calculated and results indicate that the Fano resonance has largest sensitivity.
