Abstract

Monopole and dipole scattering coefficients of a small wave size acoustic inhomogeneity are introduced. It is shown that the amplitude of these coefficients is limited. The maximum possible power scattered by the small wave size inhomogeneity is found in one-, two-, and three-dimensional cases. The number of metamaterial elements per one wavelength is estimated on this basis.
