The Rolling Motion of a Disk on a Horizontal Plane
Alexander J. McDonald, Kirk T. McDonald
Recent interest in the old problem of the motion of a coin spinning on a tabletop has focused on mechanisms of dissipation of energy as the angle alpha of the coin to the table dec…
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.
Limits on the Applicability of Classical Electromagnetic Fields as Inferred from the Radiation Reaction
Kirk T. McDonald
Can the wavelength of a classical electromagnetic field be arbitrarily small, or its electric field strength be arbitrarily large? If we require that the radiation-reaction force o…
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…
