Abstract

Using dispersive finite-difference time-domain (D-FDTD) simulations, we show that a pair of gold nanodisks stacked in a ‘sandwich’- like (end-fire) configuration produces a large enhancement of the magnetic field when irradiated with a plane optical wave, if the distance between the nanodisks is optically small. The effect, which can be rationalized in terms of a magnetic dipole resonance, is due the excitation of a hybridized asymmetric plasmon mode, in which the induced electrical dipoles in the two disks oscillate out-of-phase. The strong magnetic response, together with the simple morphology, suggests that Au nanosandwiches are suitable elementary building blocks for optical metamaterials that exhibit negative refraction.

Fig. 1.

Schematic illustration of the studied system. Two closely spaced Au nanodisks (separation d) with degenerate LSP resonance frequencies ω 0 interact vertically in the “end-fire” illumination configuration. The coupling results in two hybridized LSP modes associated with a net electric dipole moment (ω+) and a net magnetic dipole moment (ω+).

Fig. 2.
Fig. 2.

Electric (Ex ) and magnetic (Hy ) fields around Au nanodisks illuminated in the end-fire configuration (disk diameters - 88 nm, thicknesses - 24 nm). (a) Field enhancement plots for d =300 nm together with intensity enhancement spectra at two different locations (lower graph; blue and red curves for magnetic and electric fields, respectively). (b) Same as in (a), but for an inter-disk separation of d =32 nm.

Fig. 3.

Electric-field phase variation along a line parallel to the z-axis, 4 nm from the side of sandwich in the xy-plane, for the two resonance wavelengths at 575 nm - blue curve, at 700 nm - red curve. The nanodisk position are shown schematically in the background.

(a) Differential far-field scattering spectra along the three coordinate axis for the same sandwich structure as in Fig. 2b). (b) Spectral peak position and corresponding magnetic intensity enhancement factor at the mid point between the disks vs. inter-disk separation. (c) Magnetic-field intensity-enhancement vs. peak-shift relative to the non-hybridized system.
