Electro-magnetic wave generation by a linear antenna

We see the near field of a linear antenna, E-field are green arrows and magnetic field strength is shown as red shading. The current (blue) and charge (black ) distribution on the antenna (magenta) are also shown as a function of z, with positive values to the right. We see that fields in the vicinity of the antenna behave as we expect from a static picture, while further away we have to take into account the finite response time.
Fields are rescaled *r to compensate the intensity drop with distance.

A write-up of the underlying calculation is provided by Kirk McDonald.
