Abstract: Based on the interference approximation of the statistical theory of multiple wave scattering for planar systems characterized by two ordering scales, a model is proposed for calculating the coefficients of coherent transmission of $T_{\mathrm{coh}}$, reflection $R_{\mathrm{coh}}$ and the angular distribution of the intensity of scattered radiation $I(\theta)$. The components of such systems are multimers, integral and angular characteristics, which can be calculated by the method of formalism of the volume integral equation. The radial distribution function of $g_m(r)$ multimers depends on their surface concentration $\eta_m$.
It was found that dense packing of multimers results in near-orderedness, which amplification electrodynamic coupling between the multimers and manifests itself in a nonmonotonic concentration dependence of the transmission coefficient.

Keywords: finite cylinders, multimers, electrodynamic coupling, two scales spatially ordered environment, surface concentration.
