Simple, Efficient, and Switchable Perfectly Matched Layer Based on Runge-Kutta Method

Kun‐Lai Li, Chengcheng Liu, Zeyu Wang, Yongliang Zhang

A novel complex frequency-shifted (CFS) perfectly matched layer (PML) algorithm based on the Runge-Kutta method is proposed, termed the RK-iPML. The “i” in RK-iPML signifies that the algorithm is independent of the host media in the computational domain at the code level. …

Efficient Microstrip Bandpass Filter Design by a Surrogate-Model-Assisted Improved Decomposition-Based Multi-Objective Differential Evolution Algorithm

Zeyu Wang, Lu Zhang, Kun‐Lai Li, Yongliang Zhang

A one-dimensional convolutional autoencoder (1D-CAE) assisted improved decomposition-based multiobjective differential evolution (IMODEA/D) algorithm is proposed for electromagnetic (EM) optimization in microstrip bandpass filter design. The 1D-CAE is employed as a surrogate model to accelerate the design process. In addition, the convergence of …

Time-Efficient Higher-Order PML Using Bilinear Transform Without Altering Standard FDTD Formulas

Kun‐Lai Li, Yongliang Zhang, Zhengpeng Wang

This letter proposes an efficient higher-order (HO) perfectly matched layer (PML) algorithm based on the bilinear transform (BT) method for truncating finite-difference time-domain (FDTD) lattices. By rearranging the PML tensors, the resulting update formulas become a combination of standard FDTD formulas and …
