Absorbing PML boundary layers for wave-like equations Original Research Article

We consider absorbing layers that are extensions of the PML of Berenger (1994). These will be constructed both for time problems and for Helmholtz-like equations. We shall consider applications to electricity and magnetism and acoustics (with a mean flow) in both physical space and in the time Fourier space (Helmholtz equation). Numerical results are presented showing the efficiency of this condition for the time dependent Maxwell equations.
