Algebraic Way to Derive Discrete Absorbing Boundary Conditions for Wave Equation

Abstract

We introduce a new algebraic framework to derive discrete absorbing boundary conditions for wave equation in the monodimensional case. The idea is to factor directly the discrete wave operator and then use one of the factors as boundary condition. We also analyse the stability of the schemes obtained this way and perform numerical simulations to estimate their practical value.
