Abstract:Using the transfer matrix methods,the sound field formula of SH wave is derived in 1D solid solid phononic crystal , and the sound field distribution characteristic of SH wave in 1D solid solid doping photonic crystal is studied.Sound field of SH wave decreases with the increase of the propagation depth in band gap, while sound field of SH wave does not decreases with the increase of the propagation depth in conduction gap. These features help understanding to sound field distribution of the band gap and the conduction band in 1D phononic crystal.
