A series of transport experiments has been carried out in Alcator C-Mod. [Phys Plasmas 1 1511 (1994)] It is found that data from both ohmic and ICRF heated plasmas can be fitted with an L-mode scaling law. The ohmic TE's show no scaling with density in any regime and can reach values of 2-3 times neo-Alcator. Impurity confinement has been studied with the… (More)
We propose a novel mirror-image nanoepsilon (MINE) structure to achieve highly localized and enhanced near field at its gap and systematically investigate its plasmonic behaviors. The MINE can be regarded as a combination of two fundamental plasmonic nanostructures: a nanorod dimer and nanoring. By adapting a nanoring surrounding a nanorod dimer structure,… (More)
We propose and investigate a novel hybrid plasmonic rod-dimer/ring (RDR) nanostructure with significantly enhanced near-field at the gap region for its potential on sensing and trapping applications.
