Many-body wave scattering by small bodies and applications II

The many-body wave scattering problem is studied in the case where the bodies are small, $ka \ll 1$, where $a$ is the characteristic size of a body. The limiting case when $a \to 0$ and the total number of the small bodies is $M = O (a^{2-\kappa})$ is studied, $\kappa\in (0,1)$ is a parameter, the distance $d$ between neighboring bodies is $d=O(a^{(2-\kappa)/3}$.
