Abstract

The transition from localized to delocalized plasmons (i.e. the transition from a situation where the decay length of a travelling surface plasma wave is greater than its propagation distance to a situation where it is smaller) and hence the onset of plasmon delocalization is studied in a single 2D silver nanoparticle of increasing length. A fourier analysis in the near-field of the nanoparticle is used as the main tool for analysis. This method, along with far-field scattering spectra simulations and the near-field profile directly above and along the length of the nanoparticle are used to investigate and clearly show the transition from localized to delocalized modes. In particular, it is found that for a finite sized rectangular nanoparticle, both the emerging odd and even delocalized modes are nothing but a superposition of many standing wave plasmon modes. As a consequence, even very short metal films can support delocalized plasmons that bounce back and forth along the film.

Figures (11)

Fig. 1
Fig. 1

A silver nanoparticle of length L excited by an electric dipole source. The corner of the nanoparticle marks the origin. The dipole source is placed at a position of (−100nm, 20nm).

Fig. 2
Fig. 2

Analytically obtained dispersion of a 40nm thick, infinite silver film, showing the real and imaginary parts of the k-vector for even and odd propagating modes.

Fig. 3
Fig. 3

Effect of horizontal and vertical dipole sources on an infinitely long metallic nanoparticle and the resulting electric field distributions. (a) A horizontal dipole excites the even propagating mode, while (b) a vertical dipole excites the odd mode.

Fig. 4
Fig. 4

Dispersion relation computed for an L = 20µm particle, excited by a dipole source rotating from 0 to 90°. Only the even mode is excited for θ = 0° and only the odd mode for θ = 90°. (Media 1)

Fig. 5
Fig. 5

Excitation of even and odd propagating modes for a particle of length L = 20µm by a θ = 45° dipole source plotted on a base 10 logarithmic scale. Notice negative k values showing the back propagation of the surface plasmon waves.

Fig. 6
Fig. 6

Normalized scattering spectra for particles of L = 50-500nm, excited by a θ = 0° dipole source. For successively larger lengths L, higher order modes are excited.

Fig. 7
Fig. 7

Fourier analysis and scattering spectra results for L = 2.5 and 5µm. We excite the even propagating surface plasmon mode with a horizontally oriented dipole source. As can be seen, for a finite particle length, this mode is nothing more than the superposition of many higher order modes.

Fig. 8
Fig. 8

Field distribution along the line of observation points 40nm above L = 500nm and 5µm long nanoparticles. For L = 5µm, standing wave patterns are clearly seen below approximately 700THz due to interference between forward and back propagating plasmons. Only the evanescent decay of the surface plasmon is seen at higher frequencies. Even down to a very short length of 500nm, the standing wave pattern is still present.

Fig. 9
Fig. 9

Fourier analysis results for L = 1 and 5µm. We excite the odd propagating surface plasmon mode with a vertically oriented dipole source and at the same time excite a localized dipolar resonance along the 40nm height of the particle at approximately 880THz. As can be seen, for L = 1µm the propagating mode is mainly confined to approximately 820THz where the propagating plasmon is most efficiently excited and as the particle length is increased to 5µm it is found to spectrally broaden.

Fig. 10
Fig. 10

Field distribution along the line of observation points 40nm above nanoparticles of L = 1 and 5µm. For both lengths, the localized dipolar resonance along the 40nm height of the particle is seen at approximately 880THz. For L = 1µm, a clear standing wave pattern, due to the odd propagating mode, is seen at about 820THz. For L = 5µm, the standing wave extends down to lower frequencies as the mode is broadened.

Fig. 11
Fig. 11

Field distribution along the line of observation points 40nm above particles of lengths L = 250nm and 500nm. Even for these short lengths, the standing wave surface plasmon at around 820THz (also in Fig. 9) is still present.
