An interactive graphical visualization of a couple of radiation intensity functions.
In chapter 4 of Balanis' "Antenna Theory: Analysis and Design", are some discussions of the kr < 1, kr = 1, and kr > 1 radial dependence of the fields and power of a solution to an infinitesimal dipole system. This discussion severely lacks some plots. Here's a Mathematica Manipulate that allows for inspection of the real and imaginary parts of these functions, plotted against both k and r, with a kr == constant contour overlaid on it. The value of that constant can be altered using one of the sliders, as can the maximum range of k and r, and upper and lower bounds of the value of the functions being plotted.
This is a Manipulator to show the far fields of a superposition of electric and magnetic infinestismal dipoles on the x and y axes respectively. The fields at one point on the surface can be controlled using the theta and phi sliders.
A manipulate for visualizing the polar pattern for a long electric dipole.
A manipulate to show the radiation intensity of the array factor in 3D for the corner cube configuration. This doesn't include any contribution from the field itself (i.e. no sine squared term.)
Deployed CDF manipulator for Chebychev polynomial exploration.
Manipulate to visualize the variation with d for an N = 4 Chebychev fitting.
