Aalborg Universitet Near-field electrospinning of dielectric-loaded surface plasmon polariton waveguides
... techniques, such as metal stripes [3–5] and v-grooves [6,7] have already been investigated. The strong lateral confinement can be also achieved by depositing polymer stripes on a metal surface and using them as waveguides [8–11]. Near field investigation of such dielectricloaded SPP waveguides (DLSP ...

Planoconcave lens by negative refraction of stacked subwavelength
... Taking advantage of previous numerical simulations of the structure dispersion diagram, see the inset of Fig. 1 [21], it follows that a first band of the stacked sub-wavelength hole array structure emerges around the EOT frequency and it clearly shows a negative slope, i.e. phase velocity opposite t ...

Observation of preferred instability modes in a mechanically
... Stability loss in thermal plumes pertains to a broader class of problems namely stability analysis of open systems (jets, wakes). The primary mechanism that makes initially laminar flows become turbulent is the initial growth of very small disturbances. The study of these instabilities is commonly a ...
