Abstract
In this paper, the three-dimensional locally one-dimensional finite difference time domain (LOD-FDTD) method is extended to include lumped elements calculation. The algorithm of the three-dimensional (3-D) LOD-FDTD which includes lumped elements calculation is derived, and then, a complex metal cavity feed by a voltage source with lumped resistance and loaded by a lumped load is simulated. The numerical result is presented to show the validity of the algorithm. The proposed LOD-FDTD method is found to use less CPU time comparing with traditional finite difference time domain (FDTD) method.
