Abstract

The absorption of visible light by silver nanoparticles in two-dimensional arrays is investigated using a finite difference time domain algorithm. The results of the calculations show that for all shapes considered, spheres and triangular and rectangular prisms, there is reduced absorption when the particles become more densely packed within the array. The effect is seen to be more pronounced for rectangular and triangular prisms. Investigation of the electromagnetic field very close to the tip of the prism shows that the intensity is very sensitive to the separation between the nanoparticles, with the electric field increasing significantly as the spacing between the particles reduces.
