Abstract: The study concerns with defining effective medium parameters- such as refraction index, impedance, mass density and compressibility- of acoustic metamaterials via an inverse method with and without taking of visco-thermal effects into account. This is… read more here.

Abstract: Potential applications of negative-index acoustic metamaterials are strongly limited by absorptive effects of different origin. In this context, we present an investigation of the visco-thermal effects on the acoustic properties of double-negative metamaterials based on… read more here.
