A new implementation of a perfect matched layer with an auxiliary differential equation (ADE‐PML) is presented for the higher‐order finite‐difference time‐domain (FDTD) method. The implementation of the ADE‐PML is more straightforward and more memory saving than that of the traditional PML. A two‐dimensional (2D) case and two 3D cases with different microwave circuit components are designed to analyse the absorbing performance of the ADE‐PML and the simulation results show that the ADE‐PML can provide a quite satisfactory absorbing boundary condition.
