Efficient algorithm for the unconditionally stable 3-D ADI-FDTD method

This letter presents a new efficient algorithm for the unconditionally stable three-dimensional alternating direction implicit finite-difference time-domain (3-D ADI-FDTD) method. The algorithm involves updating equations whose right-hand sides are much simpler and more concise than those in the con...
