This paper deals with the active control of progressive waves of a simply supported, lossless, thin distributed-parameter planar structure. It is the purpose of this paper to present a novel active wave control method for blocking the progressive wave, and thus a quiet zone (a specific region where vibration is to be prohibited) is produced. It is also the purpose of this paper to present a means to visualize wave propagation of the structure, whereby control effect for suppressing power flow in terms of vibration intensity, progressive waves, reflected waves and the combination of thereof becomes evident.
