Performance of convolutional perfectly matched layers for pseudospectral time domain poroviscoelastic schemes

► CPML implementation for poroviscoelastic equations in anisotropic media. ► Runge-Kutta time integration scheme and pseudospectral derivative operator. ► Confirmation of advantage of the CPML for waves at grazing incidence. ► Anisotropic media require a larger number of absorbing layers than isotropic media.
