This is shown by three alternating matrix updates (no for loops except for time update) in groups of two (for H) and one (for E) spanning entire spatial grid inside a main for-loop for time update spanning the entire time-grid.Frequency-Domain Circuit Solver and Schematic Editor Build a matching network or corporate feed network and see its impact on full-wave results.

Here, H-fields i.e Hx and Hy are updated every half time-step and E fields i.e Ez are updated every full time-step. Also, the time update is done using Leapfrog time-stepping. More precisely, the Hx part is defined at every half y-coordinate and full x-coordinate and the Hy part is defined at every half x-coordinate and full y-coordinate and E fields i.e the Ez part is defined at every full x and full y-coordinate points. The H fields are defined at every half coordinate of spacesteps. The field points are defined in a grid described by Yee's algorithm.
The update is done using standard update equations obtained from the difference form of Maxwell's curl equations.
