The preferred embodiment of the present invention is generally comprised of a plurality of panels of generally wave form. The invention is manufactured by attaching the top surface of one panel to the bottom surface of another panel in such a fashion that the period of the wave form of each panel is 180.degree. out of phase with any panel juxtaposed with it, creating a plurality of passageways.
