COMPUTER SIMULATIONS OF OPTICAL PROPERTIES OF TRIANGULAR GOLD NANOPARTICLE DIMERS
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 the electromagnetic f eld enhancement upon excitation of the longitudinal surface plasmon resonance mode is localized in the gap between the particles and reaches the value | E | / | E 0 | = 58.
