Abstract
When a metallic nanostructure is illuminated by ultrashort light pulses, the excitation of surface plasmons is observed along with subsequent strong enhancement of the electric field in the vicinity of the nanostructure. This localized surface plasmonic resonance is exploited to generate coherent extreme ultraviolet light and soft-X ray by interacting noble gas atoms with femtosecond laser pulses. The resulting field enhancement is much affected by the 3-D shape of the used nanostructure, so various nanostructure shapes are examined through finite-difference time-domain analysis to predict their performance in high harmonic generation.
