This work investigates acoustic wave transmission property through a zero index metamaterials (ZIM) waveguide embedded with a general solid defect. Total transmission and total reflection can be achieved by adjusting the parameters of the solid defect. Compared to the previous study of liquid defects, our work comprehensively studies how transverse wave speed of the solid defect affects the acoustic wave propagation through the waveguide. The necessary condition of realizing total reflection by tailoring transverse wave speed is given. Thus, our work provides more possibilities to manipulate acoustic wave propagation through ZIM.
