Abstract

A theory of many-body wave scattering is developed under the assumption a << d << λ, where a is the characteristic size of the small body, d is the distance between neighboring bodies and λ is the wave-length in the medium in which the bodies are embedded. The multiple scattering is essential under these assumptions. The author’s theory is used for creating materials with a desired refraction coeﬃcient. This theory can be used in practice. A recipe for creating materials with a desired refraction coeﬃcient is formulated. Materials with a desired radiation pattern, for example, wave-focusing materials, can be created.
