Sound Scattering by a Flexible Plate Embedded on Free Surface

Figure 7

The variation of the optimised scattering cross-section with the sound frequency for (a) hinged and (b) clamped plates, where the cross-section ratio is defined as . The symbols denote the actual computed values, and the lines are best fitted to those values using polynomials of 8th order. The rest of the conditions are as in Figure 4.
