Saw this on BoingBoing.net recently: http://www.falstad.com/mathphysics.html
There is some great stuff regarding RF. First check out the Oscillations and Waves simulations. These sims can help you understand how waves travel through space. The 2-D Ripple tank shows some interesting effects, including refraction and reflection. And the Electrodynamics sims show some great stuff, including electrical, magnetic, and current in an RF wave. The 2-D simulation, http://www.falstad.com/emwave2/ has some predefined simulations including waveguides and a parabolic reflector. Definitely worth a look! -Mike O. PS: SOCALWUG meeting this Thursday! We don't have solid commitment from the presenter, but we'll have something interesting no matter what. :)
