Abstract:

We perform a detailed stability analysis based on the unsplit-field uniaxial perfectly matched layer PML formulation. Our finding shows that it is essential to have transverse field gradients present at all times to stabilize PML calculations. In the absence of transverse field gradients, the PML method becomes unstable with the axial field components growing linearly in time.
