Figure 1
Setup and conventions for the scattering problem solved with the T-matrix approach. A plane wave with a wavevector k₀ with incident angles ( $[\theta_{\rm i}]$ , $[\phi_{\rm i}]$ ) interacts with N spherical atoms, each with individual location (for example, atom p at d_p), radius ( a_p) and electrostatic potential strength ( n_p). The scattered wave is observed at observation point P at r in the global reference frame and at individual distances in the local reference frame of the spheres (for example, $[|{\bf r}_{p}|]$ ). See discussion in the text for additional details. In practice, the incident plane wave is taken along the +z axis and the structure oriented accordingly.
