Unconditionally stable leapfrog ADI-FDTD method for lossy media

Unconditionally stable leapfrog ADI-FDTD method for lossy media

This paper presents an unconditionally stable threedimensional (3-D) leapfrog alternating-direction-implicit finite-difference time-domain (ADI-FDTD) method for lossy media. Conductivity terms of lossy media are incorporated into the leapfrog ADI-FDTD method in an analogous manner as the conventiona...
