Surface plasmon polariton modes in coaxial metal-dielectric-metal waveguides
2016
New Journal of Physics
We explore the optical properties of a coaxial plasmonic metamaterial consisting of hollow dielectric cylinders with a diameter of 100-250 nm and a ring wall width of 10-50 nm, embedded in metal. We investigate the modal electric and magnetic fields and dispersion relation for different geometries and material choices of a single coaxial channel by using realistic values for all design parameters. The Fabry-Pérot modes of a finite thickness slab are investigated with cathodoluminescence
