Novel Design

We propose a novel design of a broadband plasmonic nanoantenna, investigate it numerically using finite-difference time-domain methods, and explain its performance using the analysis of charge distribution in addition to a multipole expansion.

Difference Time

The optical properties of triangular gold nanoparticle pairs are investigated by numerical simulations using Finite-difference time-domain (FDTD) method. The simulation results show the significant red shifts of plasmon resonances as the size of nanoparticle is increased. The large electric field enhancement is also verified by calculating the local electric field distributions.
