Efficient and unconditionally stable formulations of the anisotropic perfectly matched layer are presented for truncating double negative (DNG) metamaterial finite difference time domain (FDTD) grids. In the proposed formulations, the state‐space equations are employed in the alternating direction implicit FDTD algorithm to obtain update equations for the field equations in the DNG metamaterial domains. Numerical example carried out in one‐dimensional Lorentzian type DNG metamaterial domain is included to show the validity of the proposed formulations. © 2006 Wiley Periodicals, Inc.
