From: The time-domain Cartesian multipole expansion of electromagnetic fields
Normalized norm of the electric field obtained from the imaging experiment at \(t=0\) and \(x_3=0\). Three electrical sizes are illustrated along the three columns. The rows indicate the truncation order n. The current density, whose outline is illustrated, is obtained by splitting the letter “E” into five rectangles whose amplitudes and polarities are also indicated in (d).
