Hertzian Dipole Radiation via the Weizsacker-Williams Model
Kirk T. McDonald, Max S. Zolotorev
We use the Weizsacker-Williams method to deduce the radiated power, and its angular distribution, emitted by an electron of charge that undergoes simple harmonic motion.
A bounded source cannot emit a unipolar electromagnetic wave
Kwang-Je Kim, Kirk T. McDonald, Gennady V. Stupakov +1
We show that a bounded source cannot produce a unipolar electromagnetic pulse. As a consequence, there are no three-dimensional electromagnetic solitons in vacuum.
Energy Balance in an Electrostatic Accelerator
Max S. Zolotorev, Kirk T. McDonald
The principle of an electrostatic accelerator is that when a charge e escapes from a conducting plane that supports a uniform electric field of strength E_0, then the charge gains…
Time-Reversed Diffraction
Max S. Zolotorev, Kirk T. McDonald
We show that a time-reversed formulation of Huygens-Kirchhoff diffraction can be used to deduce the transverse and longitudinal fields of a Gaussian laser beam, starting from a sim…
Classical Radiation Processes in the Weizsacker-Williams Approximation
Max S. Zolotorev, Kirk T. McDonald
The main features of radiation by relativistic electrons are well approximated in the Weizsacker-Williams method of virtual quanta. This method is best known for its application to…
