Using the boundary conditions, the SH wave transfer matrix is derived in multilayer dielectric system and the SH wave transmissivity in 1D solid solid phononic crystal is obtained. Using the transmissivity to study the filter characteristics of total reflection tunnel effect of the SH wave in 1D solid solid phononic crystal. SH wave total reflection tunnel effect in 1D solid solid phononic crystal is found and SH wave total reflection tunnel effect have good filter characteristics.
