Figure 1: Scattering configuration.
A homogeneous sphere dimer of radius R (=R1=R2) is illuminated by a monochromatic plane wave propagating along the z axis and linearly polarized either parallel to the dimer connecting axis: (a) longitudinal configuration (P), (b) transverse configuration (S). The gap distance is denoted by d and the interaction parameter by d0=d/R. θ corresponds to the scattering angle.
