“…The evolution of the dip A in the mode maps (see Figure 2) is quite flat and very close to TE 21 Mie mode. This fact suggests that dip A is related with TE 21 resonance of isolated sphere.…”

“…In a previous work studying the evolution of the transmission spectra of these structures with positional disorder [25], dip G was identified as significantly less tolerant to disorder, disappearing in lattices were other ones (F, B or C) remained clearly observable. From all this we conclude that dip G can not directly related to a single Mie mode TE 21 and is highly dependent on the lattice structural arrangement. Finally we present the simulation results for the dip H ( Figure 7).…”

“…Furthermore, we can observe in Figures 3(a) and 3(b) how the dip A is near to TE 21 mode in every compactness cases studied, but this proximity slightly varies from one f f value to other. These correspondences suggest that the characteristics of TE 21 Mie resonances for an isolated sphere indeed appear in the dip A, although the data derived from electric-field distribution are not conclusive.…”

“…For dip G, Figures 6(e) to 6(g) present the distributions of electricfield intensity in samples of different compactness. We can observe that the internal electric-field distribution of the samples does not resemble any of the closer Mie modes: TM 11 , TE 21 (Figures 4(c) and 4(d)) or TE 11 ( Figure 6(d)). However, the electric field distribution of dip G is similar to the one of dip A.…”

“…The enhancement between the spheres is considered to be due to the strong interaction in close packed system [9]. Especially remarkable is the apparent mismatch in the field distribution between dip A and TE 21 and TM 11 Mie modes whose field distribution show two peaks inside the spheres (see Figures 4(c) and 4(d)). However, it can be noticed some similarity between the distributions in Figure 4.…”

Abstract-The internal electric-field distribution from single layers of dielectric spheres with high refractive index (n = 2.65) has been analyzed for a number of different compactness cases by FDTD (FiniteDifference Time-Domain) method. The field distributions from the transmission spectra were compared with the internal electric-field distribution of the Mie modes of an isolated sphere. In general, the agreement is very good in almost all cases studied. The results show that TE and TM Mie modes are the origin of the resonances in the transmission spectra of the single layers. The resonances of the monolayer attributed to TE 11 and TM 11 Mie modes are only excited for compactness values lower than 0.38, suggesting a dependence of periodical arrangement effects for these modes. Moreover, the field distribution corresponding to some of the dips in the spectrum cannot be directly attributed to Mie modes (TE 21 ). The result indicates these are formed by degenerated or weakly coupled Mie modes induced by the periodic structure.

Much attention has been focused recently on the preparation of macroporous materials by templating with colloidal crystals. This interest stems from the important properties of such microstructures, which have a wide range of applications including sensors, catalysts, and photonic crystals. Various macroporous and mesoporous materials have been made via this process, including ceramics, [1±9] carbon, [10,11] chalcogenides, [12±14] NaCl, [3] polymers, [15±19] and silica±gold. [20] The extension of such a material patterning method to metals is particularly attractive, as metals with ordered microstructures exhibit unique optical, electrical, magnetic, and catalytic properties. For example, surface enhancement of Raman scattering in porous gold films has been demonstrated by Tessire et al. [21] In a recent study, Baumberg and coworkers reported the observation of confined plasmons in gold nanocavities. [22] Although the adaptation of the templating method to the preparation of porous metal films is limited, several strategies have been reported, including precipitation/chemical conversion, [23,24] direct penetration of metal nanocrystals, [25] electroless deposition, [26,27] and electrochemical reduction methods. [28] When monodispersed silica spheres are used as the sacrificial elements, annealing of the colloidal crystal is usually performed at high temperatures. This results in the formation of small necks between neighboring spheres, which makes the template stable during the material patterning process.[26±28] A complete filtration of metal into the free spaces of the template has been successfully demonstrated using these approaches, which result in macroporous metal films that are an exact replica of the sacrificial templates. In this communication we report for the first time the preparation of ordered arrays of hollow metal spheres by colloidal crystal templating. However, instead of using annealed silica colloidal crystals as templates, [26±28] we use polymer colloidal crystals. Moreover, the template is confined between two substrates in order to preserve its ordering in the material-patterning process, as described by Xia and coworkers. [29] We combine a seeded growth technique for metal coatings on isolated colloids in solution and the confined template-directed synthesis method for material patterning. The samples we obtain are were two-dimensional (2D) and three-dimensional (3D) ordered hollow silver spheres prepared by templating against the monolayer or the multilayer of hexagonal close packed polymer beads, respectively. The schematic procedure of our experiment is depicted in Figure 1. The starting material is an ordered colloidal crystal consisting of polystyrene (PS) beads, which was prepared using a modification of the micromolding method reported by Kim et al. [30] Specifically, a microchannel was first formed between two glass slides that were separated with two identical spacers. Upon dipping into a colloidal dispersion solution, the microchannel was spontaneously filled with the colloi...
