Abstract

In this paper the properties of a “bowtie” nanostructure formed by a pair of distorted triangular nanoparticles are investigated using computer simulation. It is shown that the electromagnetic field enhancement upon excitation of the longitudinal surface plasmon resonance mode is localized in the gap between the particles and reaches the value \({{\left| E \right|} \mathord{\left/ {\vphantom {{\left| E \right|} {\left| {{{E}_{0}}} \right|}}} \right. \kern-0em} {\left| {{{E}_{0}}} \right|}} = 58.\)
