Run a new FDTD analysis with a fixed maximum number <b>Fixed Maximum Number of time steps Time Steps</b> equal to 2,500 and wait until it is completed. Open the data manager and plot the data file "Probe_1_X_H_Time.CPX" in EM.Grid. Note that due to the special nature of [[EM.Tempo]]'s periodic FDTD formulation, the time-domain fields are complex-valued. By contrast, the time-domain fields of regular aperiodic structures are real-valued. The figure below shows the X-component of the magnetic field at the right edge of the metallic strip as a function of time. This is proportional to the surface current flowing at the edge of the strip. You can see from the figure that the waveform dies off over time. so it converges and doesn't oscillate.
