A new two-way artificial boundary condition for wave propagation
We propose a new formulation of a two-way artificial boundary condition for the wave equation in mixed form. We justify appropriately the idea behind the formulation of the two-way artificial boundary condition. To exhibit the capabilities of the two-way artificial boundary condition we perform a se...
