Retard may be embedded within your own web page with the following HTML tags:
<applet code="Retard.class" width=600 height=400> <PARAM NAME="FPS" VALUE=20> <PARAM NAME="dynamics" VALUE="Wiggler"> <PARAM NAME="speed" VALUE=0.5> <PARAM NAME="resolution" VALUE=2> </APPLET>
where speed is the maximum speed of the source. The dynamics parameter determines the trajectory of the electron. It can take on values of Wiggler, SHO, Sync or Intertial. The resolution parameter determines how often field lines are recalculated. Setting this parameter too large may result in unphysical results such as electric field lines crossing.
Retard may be scripted using the following Java method calls:
