Retrieving Effective Acoustic Impedance and Refractive Index for Size Mismatch Samples

In this paper, we have presented an analytical solution to extract the effective properties of acoustic metamaterials from the measured complex transmission and reflection coefficients when the metamaterial and impedance tube have different sizes. We have first modeled this problem as a bilayer meta...
