Abstract :
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.
