Abstract We investigate the propagation properties of hetero-phononic crystal waveguides by the improved eigen-mode matching theory, which can be used
at same time to calculate both the transmission (reflection) coefficient and band structure. The numerical results show that the transmission frequency range is the same as the common range for two uniform waveguides composing the hetero-system, and the gap of any composite waveguide is also the gap of the hetero-phononic crystals waveguide.
