2-D TE Electrodynamics is a free and Java based physics simulation that demonstrates electrodynamics in two dimensions, including setups which demonstrate reflection at conductors, electromagnetic waves, radiation from antennas, standing waves, waveguides, and diffraction.

To get started with the applet, just go through the items in the Setup menu in the upper right. The arrows indicate electric field (and current, in the gray conductors); the green and red indicate magnetic field.
