This paper derives the reflection coefficient formula of the perfectly matched layers(denoted asPML)for the numerical simulation of the acoustic wave equation,based on the plane wave theory and the second-order accuracy spatial difference scheme.Then,the impact of the theoretical reflection coefficient Ron the absorption effect of the PML is analyzed.The experimental results demonstrate that,for the incident wave with a small incident angle(less than 30°),when Ris equal to 10-4,the PML absorbing boundary co...
