| Research Abstract |
To investigate localized surface plasmons excited on periodically arranged metal nanoparticles, we develop a numerical algorithm for solving the light scattering by a two-dimensional periodic array of clusters consisting of nanoparticles having arbitrary shapes, and we numerically confirm the collective surface plasmon resonance associated with the periodicity of metal nanoparticle arrays. We try to periodically arrange metal nanoparticles in a liquid by use of the radiation pressure of ultrasonic waves, but we have not yet confirmed the diffracted light by the periodic structures.
