Wave scattering by many (M = M(a)) small bodies, at the boundary of which an interface boundary condition is imposed, is studied.

Smallness of the bodies means that ka << 1, where a is the characteristic dimension of the body and k = 2&#x03C0; &#x03BB; is the wave number in the medium in which small bodies are embedded.

Equation for the effective field is derived in the limit as a 0, M(a) →∞, at a suitable rate.
