This java applet is a simulation that demonstrates
magnetostatics and electrodynamics in two dimensions, including
setups which demonstrate electromagnetic waves,
reflection at conductors, reflection and refraction at dielectric
boundaries, dipole and quadrupole
radiation, dispersion, induction, eddy currents, standing waves,
waveguides, and diffraction.
To get started with the applet, just go through the
items in the Setup menu in the upper right.
This is the TM version of the applet. There is also a
