Producing EB Waves: Accelerating and Decelerating Particles

[jse7]

How does a charged particle, that is accelerating or de-accelerating, produce an EB wave? What is actualy happening when an EB wave is produced? The EB wave has energy, what is happening to the energy of the charged particle? Is the charged particle slowing down, if so why is an EB wave produced for a de-accelerating particle as well?

Charged particles don't accelerate or decelerate by themselves. They do so in response to some external force. So the energy that is radiated away can come either from some of the particle's kinetic energy, or from work done by the external agent, or both.

In a circular electron accelerator (synchrotron) or storage ring, the radiated energy shows up in the accelerator's electric power bill.
