Acoustic Metamaterials & Structural Dynamics
Acoustic Black Hole (ABH) Power-Law Taper & Vibration Damping Calculator
Model 1D/2D power-law thickness profile ($h(x) = \epsilon x^m$), local flexural wave deceleration ($c_g(x) o 0$), reflection coefficient ($R$), and structural vibration attenuation for lightweight aerospace panels.
ABH Geometry & Material Inputs
Uniform panel thickness before ABH indentation.
Radius of circular 2D ABH pit or length of 1D wedge.
Exponent for $h(x) = \epsilon x^m$ (typically $m \ge 2$ for zero wave reflection).
Manufacturing CNC limit thickness at central apex / tip.
Loss factor of central damping layer tape (e.g. 3M VHB or polyurethane).
Target structural vibration frequency range.
