Abstract In some cases, perfectly matched layers (PML) with quartic conductor profiles are superior to the traditional quadratic gradations. This PML boundary condition can be applied to gratings; it does not suffer from Fabry‐Perot fringes and is not swamped by noise, unlike the absorbing boundary condition. © 1995 John Wiley & Sons, Inc.
