This java applet is a simulation that demonstrates
electrodynamics in two dimensions, including
setups which demonstrate electromagnetic waves,
reflection at conductors, 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.
This is the TE version of the applet. There is also a
TM version.
