A survey of passive wave absorbers

One of the most common laboratory effects that plague physical model experiment is reflection of wave energy from boundaries or from model structures, and dealing with wave reflection tanks right behind wave generation in importance to high quality laboratory experiments. A through survey of passive wave absorbers by authors indicate that parabolic longitude profile decrease reflection and combined with progressively wire mesh screens of progressively decreasing porosity spells a minimum reflection which its length can be constructed less than one-wave length. The efficiency can be increased by utilizing gravel and stones.
