title = "Channel drop process of elastic wave in a two dimensional phononic crystal",
abstract = "We study theoretically the possibility of transferring acoustic waves of a given wavelength between two parallel guides created in a phononic crystal. The structure considered in this work is composed of a periodic array of steel cylinders in water that displays an absolute bandgap. Within this gap, a full transmission band exists for propagation inside a straight wave guide. We show that by choosing an appropriate coupling structure between two parallel wave guides, one can transfer a particular acoustic wavelength from one guide to the other. The coupling element is composed of two hollow cylinders interacting with four other hollow cylinders located at each side of the wave guides. We discuss how the demultiplexing phenomenon is affected by varying the inner radius of the hollow cylinders.",
