Top part: mean value of the reflection coefficient modulus for optimized ABHs with shape function described employing cubic splines with different number of control parameters. Bottom part: the case of non-optimized linear shape function, and optimized power-law shape function; N = 500, ξ = 0.5, Rmin = 0.25 mm.
