Minimum and maximum density values of the reflected wave after the interaction with different CH shapes (circle, ellipse, convex, concave symmetric, and concave asymmetric), considering an initial incoming wave profile with ρIAE = 1.1 for the initial enhanced amplitude, ρIAD = 0.8 for the depleted amplitude, ρIWE = 0.2 for the initial width of the enhanced part, and ρIWD = 0.4 for the initial width of the depleted part.
| CH shape | ρmax of reflection | ρmin of reflection |
|---|---|---|
| Circle | ≈1.06 | ≈0.78 |
| Ellipse | ≈1.07 | ≈0.76 |
| Convex | ≈1.13 | ≈0.74 |
| Concave symm. | ≈1.2 | ≈0.74 |
| Concave asymm. | ≈1.24 | ≈0.73 |
