The leapfrog alternating direction implicit finitedifference time-domain (ADI-FDTD) method, as an effective implementation of ADI-FDTD, has garnered widespread attention and extension. However, it has been found that the commonly used leapfrog ADI-FDTD method for lossy media exhibits field leakage...
