Abstract
The feasibility of using a pitching porous plate to actively control water waves is investigated on the basis of the linearized wave theory. The two-dimensional problem is formulated to deal with a fully submerged porous plate, pitching about its middle point and scattering an incident monochromatic wave. The pitching amplitude is assumed to be small, while the frequency of pitching is kept the same as that of the incident wave. The porous flow through the plate is governed by Darcy's law. The method of matched eigenfunction expansions is used to analyze the heights of reflected and transmitted waves. It is found that the heights of reflected and transmitted waves vary rapidly for small values of porous-effect parameter. A small value of porous-effect parameter is found to be optimal to dissipate incident wave energy.
