I've been developing some digital movies that illustrate radiation from simple radiators, that are described below. Chiefly, these were prepared using MathSoft's MatLab and Adobe Premiere, although some used MathCad's capabilities.
They can be viewed on-line (slow) or downloaded for later viewing. In order to facilitate downloading, the filename has been changed from ___.avi to ___.doc. After downloading, rename them as *.AVI files to run them on your PC.
Many cases show the same phenomena, called Case 1: The magnitude of end-fire radiation from two isotropic radiators--4x4 wavelengths for 1 period.
I'd really appreciate any feedback from viewers if you find one
method of presentation better than another.
