Description :-
1D FDTD without for loops (vector updates)-
The 1D TEM wave is x-directed z-polarized TEM wave containing the y-directed magnetic field Hy and z-directed electric field Ez. The time update in Yee Algorithm is done using Leapfrog time-stepping. Here, the H fields are updated every half time-step and E fileds are updated every full time-step. This is shown by two alternating vector updates spanning entire spatial grid inside a main for-loop for time update spanning the entire time-grid. Yes, there are No For Loops except for timesteps.
