Abstract: Mode of elastic wave in 1D solid-liquid cylindrical phononic crystal is obtained with restriction conditions of elastic wave.Bandgap of elastic wave is calculated with dispersion function.New structure of bandgap in 1D solid-liquid cylindrical phononic crystal is revealed.Bandgap of 1D solid-liquid cylindrical phononic crystal is determined with quantum number of mode and cylindrical radius.

Key words: cylindrical phononic crystal, restrictions, bandgap, mode
