Investigation of multiplexed plasmonic structure metamaterials with equivalent transmission line model

ORAL

Abstract

We report our investigation of multiplexed structure metamaterials with the equivalent coupled transmission line model. In this metamaterials, two plasmon resonance elements are multiplexed in each unit cell of the periodic structures. Symmetrically multiplexed structures give increased spectral bandwidth and the non-symmetrically multiplexed structures give the band splitting property. By varying the gap size between the multiplexed elements, we find the plasmonic coupling affects the spectral property of the multiplexed structure metamaterials. We have developed a coupled transmission line model that can successfully model the multiplexed structure metamaterials when far-field coupling dominates, but the coupled transmission line model cannot describe the multiplexed plasmonic structures when the strong near-field coupling occurs.
