Abstract

On aggregation, two identical spheres produce split resonant structures so broadened as to be observable even if their (single) progenitor resonances are narrow beyond detectability.

Comparison of resonance spectra of two cooperatively scattering spheres with that of a single sphere.

Fig. 2

Influence of different sets of normal modes on the resonances of a bisphere. The curve labeled Exact was generated by summing the contributions of the normal modes of the bisphere through the first sixty-five terms. (This corresponds to Trncpt = 65.) Convergence of the series is good to within ≈ 0.03% or better. The error incurred if the bisphere expansion is truncated at the same mode order as the Mie series of one of its constitutents is displayed by the curve labeled Trncpt = 40. The other two curves are the results of suppressing one or both of the progenitor resonances. [Reciprocity dictates that the results for the case a39(2) = 0 are the same as for a39(1) = 0.]

Dominant mode approximation of scattering by two spheres compared to the intensity that would be scattered by a single sphere if only the TE 39 ( 1 ) mode contributed to the spectra. The scattering geometry is shown in the insets of the two previous figures.
