Acoustic wave propagation in fluid metamaterial with solid inclusions
Abstract
Acoustic waves propagation of in composite of water with embedded double-layered silicone resin/silver rods is considered. Approximate values of effective dynamical constitutive parameters are obtained. Frequency ranges of simultaneous negative constitutive parameters are found. Localized surface states on the interface between metamaterial and "normal" material are found. Doppler effect in metamaterial is considered. Presence of anomalous modes are shown.
