Abstract

The spectral response of crescent-like metallic nanostructures, a sub-class of U-shaped split-ring resonators, on a glass substrate at normal incidence is studied numerically. Also, the interpretation of transmission resonances arising from periodic conventional standard split-ring resonators with rectangular edges (SSRR) at normal incidence is revisited. In particular, we focus on one specific transmission resonance which is present for nano-crescents (NC) but absent in the case of SSRRs used for metamaterials. It is proposed that for a U-shaped metallic structure of arbitrary geometry, coupling of plasmonic eigen modes at all the surfaces of the three-dimensional structure is essential to be considered. The manner in which the coupling takes place between plasmonic modes at all the surfaces of the three-dimensional structure is what completely characterizes transmission resonances, and it is unique for each given resonance.

Fig. 1

Unit cells of two different types of periodic U-shaped nanostructures: (a) single-slit split-ring resonator (SSRR), (b) nano-crescent with rectangular inner boundaries (NCR). Incident light is linearly polarized along the x axis and propagates in the + z direction.

Fig. 2

(a) Comparison between transmission spectra of periodic NCR (crescent shaped structures with a rectangular inner void) and conventional SSRR structures of same lateral depth (dr = 45 nm). Figures (b) and (c) show the transmission and reflection spectra for NCRs with different values of dr . The numbers 1, 2 and 3 are labels for the different resonances arising in the transmission/reflection spectra.

Behavior of transmission resonances(denoted as 1, 2 and 3) of NCR (t = dr = 45 nm) with a variation in the refractive index of substrate (nsub ).

(H)-field (array of red cones on left-side pictures) and Ez -field (colored map in right-side patterns) distribution of the NCR with thickness t = dr = 45 nm at different resonance conditions. (a) Two slices 1' (xz plane) and 2' (yz plane) onto which the vector magnetic field is projected. Points A and B denote the sharp edges of the NCR structure, whereas C is the cross-section of the bottom part. (H)-field projections on planes 1' and 2', and Ez distribution (from left to right) are shown for (b) mode 1, (c) mode 2, and (d) mode 3, respectively. The sizes of the red cones are proportional to the magnitude of projected (H) field. The white arrows merely represent the current flow direction in the respective arms of the NCR as deduced by the (H)-field projections for modes 1 and 2. The Ez component is color-coded, with red corresponding to positive and blue to negative values, respectively.

(H)-field distribution on plane 1' (as shown in Fig. 3(a)) for NCR structures with different lateral depths (dr ): (a) 30 nm, (b) 45 nm, and (c) 60 nm at mode 2 condition.

Plasmonic mode distribution (total Ez field) at the front (metal-air) and back (metal-glass) interface at different mode conditions of SSRR (dr = t = 45 nm). Labels z1 and z2 denote xy planes situated at a distance of 20 nm from the SSRR, in air and glass, respectively.

Plasmonic mode distribution at the top-bottom and lateral surfaces of the SSRR: (a) Ey plots for the top (y = y1 ) and bottom (y = y2 ) surface of the SSRR at different far-field resonance conditions. Planes y1 and y2 are 20 nm away from the respective metal surfaces. (b) Respective Ex plots for the lateral surfaces of the SSRR at the same resonance conditions.

Plasmonic mode distribution (total Ez field) at (a) the metal-air (z1 ) and metal-glass (z2 ) interfaces at different mode conditions of the NCR structure (t = dr = 45 nm). Kindly note the mismatch in the mode pattern at z1 (dipolar) and z2 (quadrupolar) for mode 2 condition.
