IEEE Transactions on antennas and propagation, 2008•ieeexplore.ieee.orgA three-dimensional unconditionally-stable locally-one-dimensional finite-difference time-
domain (LOD-FDTD) method is proposed and is proved unconditionally stable analytically.
In it, the number of equations to be computed is the same as that with the conventional three-
dimensional alternating direction implicit FDTD (ADI-FDTD) but with reduced arithmetic
operations. The reduction in arithmetic operations leads to approximately 20% less
computational time in comparisons with the ADI-FDTD method.
