Abstract
In this report, the authors present the design, fabrication and realization of coupled plasmonic cavities using metallic Moire structures. The phase shifts at the nodes of Moire pattern enable localization of SPPs resulting in a mini band in the band gap region. The authors find group velocities around V g =0.44c at the center of the mini band and approaches to zero at the edges of mini band.
