Abstract

We analyzed the realization conditions and the parameters of acoustic media suitable for realization of the negative refraction of sound waves due to multiple resonance scattering by spherical inclusions. The frequency ranges of resonant transparency windows are calculated in which the effective compressibilities and densities assume negative values and the relative level of the radiative loss is rather low.
