Improved Leapfrog LOD-FDTD Method With Controlling Parameters
IEEE Microwave and Wireless Components Letters(2022)
Abstract
An improved locally 1-D (LOD) finite-difference time-domain (FDTD) method with a one-step leapfrog scheme has been developed, and its numerical dispersion has been further optimized due to the introduction of controlling parameters. On the premise of unconditional stability, we further simplified the implementation through auxiliary field variables. Moreover, the internal relationship between nume...
