Abstract: We report rectification enhancement of acoustic waves through a double array of periodic triangular holes embedded in an elastic medium of an acoustic phonon rectifier. We numerically investigate the transmission rates of waves and hence the efficiency of the rectifier using the Finite-Difference-Time-Domain (FDTD) method. We alter the position of the arrays and investigate the optimal position for high-efficient rectification to facilitate practical applications.
