我们报告了通过嵌入声子整流器弹性介质中的周期性三角形孔的双阵列对声波的整流增强。我们使用时域有限差分 (FDTD) 方法对波的传输速率以及整流器的效率进行数值研究。我们改变阵列的位置并研究高效整流的最佳位置以方便实际应用。
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.
