title: Acoustical propagation in a prefractal waveguide.
abstract: We present a theoretical study and experimental results for an acoustic multiscattering one-dimensional system made of cylindrical tubes of different diameters whose lengths follow a Cantor-like structure. Homothetic acoustical features and forbidden bands as well as wave trapping phenomena are reported.
