This paper deals with a wave filtering method for a flexible beam using point sensors for the purpose of implementing an active wave control system. It is the purposes of this paper to present the novel wave filter which can be located at any position of the beam. Firstly, the design procedure of the wave filter using two or four point sensors is presented. When introducing four point sensors, the wave filter may be placed at an arbitrary location of the beam, while an approach with two point sensors has limitation of the sensor placement. Next, from a viewpoint of numerical analysis, the effect of near-fields on the wave filter accuracy is investigated. It is found that the newly proposed wave filter may extract the designated wave no matter how strong the near-field effect is. Finally, experiment of the wave filter is carried out, the accuracy as well as robustness of the wave filter being demonstrated.
