This
book provides a recipe
for creating materials with a desired refraction coefficient, and solves the many-body wave scattering problem for many small
impedance bodies. The physical assumptions make the multiple scattering effects
essential. Technological problems are formulated which, when solved, make the
theory practically applicable. The importance of a problem of producing a small
particle with a desired boundary impedance is emphasized, and inverse
scattering with non-over-determined scattering data is considered.
