Active Wave Absorption
As an option the wave generator can be equipped with Active Wave Absorption (AWA). With this functionality up to 90% of the height of waves traveling towards the wave generator can be absorbed. This will reduce the amount of re-reflection and hence improve the quality of the generated wave.
With AWA the maximum test duration can be increased, while the effect of unwanted low frequency oscillations is decreased. Another interesting aspect of AWA is that the time between tests can be decreased by effectively stretching the water surface.
