Staggered-Grid Finite Difference Method with Variable-Order Accuracy for Porous Media
The numerical modeling of wave field in porous media generally requires more computation time than that of acoustic or elastic media. Usually used finite difference methods adopt finite difference operators with fixed-order accuracy to calculate space derivatives for a heterogeneous medium. A finite...
