Comparison of attenuation coefficient (α) at 8.5 MHz, Young’s modulus (Y), and Pore diameter (φ) for all three configurations; Aq environment samples inserted SC and SM measured at a scan frequency of 8.5 MHz. (a) α vs. Y in SC region, (b) α vs. φ in SC region, (c) α vs. Y in SM region, and (d) α vs. φ in SM region. (e,f) represent α vs. Y and α vs. φ respectively in an Aq environment.
