Mode and Bandgap of Elastic Wave in Solid-Liquid Cylindrical Phononic Crystal
-
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.
