Abstract
Analytical expressions are presented for the wave number, the characteristic wave impedance, and the refractive index of homogeneous longitudinal plane waves propagating in an acoustic metamaterial with dissipative losses. The metamaterial is characterized by the effective scalar material parameters: the complex density and the compressibility. To distinguish between the forward and backward waves, the wave type identifier is introduced.
