The transition from a TEM-like mode to a plasmonic mode in finite-width THz parallel-plate waveguides
By the near-field measurement of the electric field distribution inside the finite width THz parallel plate waveguide, we find the transition from conventional diffractive TEM-like mode to plasmonic mode. This mode transition ...
Plasmon coupling between a gold colloid and a gold film and its implications on tip enhanced Raman spectroscopy
Engineering of plasmon resonances is important for a variety of applications, including but not limited to surface enhanced Raman spectroscopy (SERS) and near field scanning optical microscopy (NSOM). Of special interest ...
