Deep subwavelength plasmonic waveguide switch in double graphene layer structure
Deep subwavelength plasmonic waveguide switch double graphene layer structure
2015/8/7
Graphene provides excellent prospects of the dynamic tunability, low propagation loss, and extreme mode confinement for plasmonic excitations in the infra-red and terahertz frequencies.We show t...
Understanding the dispersion of coaxial plasmonic structures through a connection with the planar metal-insulator-metal geometry
coaxial plasmonic structures planar metal-insulator-metal geometry
2015/8/10
We elucidate the dispersion behavior of deep-subwavelength propagating modes in coaxial plasmonic structures by making an explicit connection with the planar metal-insulator-metal geometry. We provide...
