Radiation Simulator,
by Tsumoru Shintake.
Version on my site.
Click on image near bottom of page. I recommend turning
off the auxiliary windows, and turning on "Plot Wavefront" under "View",
"Field Plot."
Note that you can set the velocity of the charge to be greater
than 1 => faster than light.
--- The classic textbook illustration of how yanking a charge causes radiation
can be nicely simulated by choosing "Setup", "Trajectory", Line", velocity = 0.1,
start = -0.05, stop = 0.05.
--- For a dipole radiator, try "Setup", "Trajectory", "Dipole Oscillation",
velocity = 0.8, amplitude = 0.02.
--- For Ĉerenkov radiation, try "Setup", "Trajectory", Line", velocity = 1.5,
start = -1.0, stop = 1.0. You may want to turn off "Plot Electric Field Lines"
for this.
