ACTIVE DEVICES FOR THE REDUCTION OF WAVE INTENSITY

It is shown how a submerged body, which can move subject to a restoring force, can totally reflect an incident wave of a particular frequency. The theory is applied to a tethered buoyant circular cylinder and the reflection and transmission coefficients of such a device are calculated. It is shown that an appreciable amount of the incident wave energy can be reflected over a wide range of wave frequencies.
