Title of Paper:

Reduced propagation loss of surface plasmon polaritons on Ag nanowire-graphene hybrid

Journal:

Nano Energy

Summary:

The propagation loss of surface plasmon polaritons (SPPs) on metal nanowires (NW) has limited their appli-
cations in integrated nanophotonic devices. In order to reduce propagation loss, the ohmic loss and leaky ra-
diation when NWs placed on substrates should be restrained. In this work, through integration with graphene,
the ohmic loss can be decreased and the leaky radiation of hybridized plasmon modes H 1 and H 2 mode can be
prominently suppressed, resulting in the reduced propagation loss. Finite element method (FEM) has been
utilized for theoretical calculations, which matches the experimental results well. Our work demonstrates a
feasible and effective method to reduce the propagation loss.
