An efficient perfectly matched layer (PML) is proposed for waveguides. In this letter, the PML region is simulated in one dimension, which improves the computational efficiency. A WG‐90 rectangular waveguide with a thick inductive iris is analyzed by the finite‐difference time‐domain (FDTD) method with Berenger' PML and the proposed PML. Scattering parameters and computational efficiency are compared. © 1998 John Wiley & Sons, Inc. Microwave Opt Technol Lett 18: 360–362, 1998.
