Local electric field enhancement during nano-focusing of plasmons by a tapered gap
Gramotnev, Dmitri, Pile, David, Vogel, Michael W., & Zhang, Xiang (2007) Local electric field enhancement during nano-focusing of plasmons by a tapered gap. Physical Review B (Condensed Matter and Materials Physics), 75(3), 035431.
We demonstrate that during plasmon nano-focusing in a tapered gap (V-groove), local electric field experiences much stronger enhancement than the magnetic field. Two distinct asymptotic regimes are found near the tip of the groove: the electric field approaches either zero or infinity when dissipation is above or below a critical level (at a fixed taper angle), or taper angle is smaller or larger than a critical angle (at a fixed level of dissipation). Tapered gaps are shown to be the best option for achieving maximal field enhancement, compared to nano-wedges and tapered rods. An optimal taper angle is determined.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
