The Hertzian dipole is fundamental to the understanding of dipole radiation. It provides basic
insights into the genesis of electromagnetic waves and lays the groundwork for an understanding of
half-wave antennae and other types. Equations for the electric and magnetic fields of such a dipole
can be derived mathematically. However these are very abstract descriptions. Interpreting these
equations and understanding travelling electromagnetic waves are highly limited in that sense.
Visualizations can be a valuable supplement that vividly present properties of electromagnetic
fields and their propagation. The computer simulation presented below provides additional
instructive illustrations for university lectures on electrodynamics, broadening the experience well
beyond what is possible with abstract equations. This paper refers to a multimedia program for PCs,
tablets and smartphones, and introduces and discusses several animated illustrations. Special
features of multiple represe…
