This graph from BOUSS-2D's technical report illustrates the variation of effective reflectivity given various damping coefficients and damping layer widths. To use this graph:

  • Compute L (the wavelength for the incident wave).
  • Select a w/L ratio. Use this ratio to compute w (damping width).
  • Select an expected reflection percentage. Follow a horizontal line for this percentage on plot to intersect the graph for selected w/L ratio. Read associated damping coefficient from plot.
  • Note that the reflection coefficient is very sensitive to a change in damping coefficient when the coefficient is small (< 0.3) and much less sensitive when the coefficient is larger.
  • This process may require the damping parameters be changed when different wave conditions are considered.
  • It should be observed that this plot is for normally incident waves. Different reflection coefficients would be obtained for obliquely incident waves.
