Abstract

Theoretical calculations show that the symmetric, anti-symmetric, and multipolar plasmon modes can be excited in perfect and non-concentric graphene nanorings. Meanwhile, strong electromagnetic-field concentration is also achieved, which has comparable enhancement factor with graphene nanodisks.
