Figure 1: The figure shows a Lorentz contracted charged particle with proper radius moving to the right with velocity . The field is observed at a point of time , and at this moment the centre of the particle is at the position . The circle is a field front produced at the retarded point of time when the centre of the particle was at the position . The field front is chosen such that it just touches the front of the particle. The Schott energy is localized in the shaded region between the field front and the ellipsoid representing the surface of the particle. In the figure the velocity is chosen to be .
