Abstract
Electromagnetic particle simulations solve the full set of Maxwell’s equations. They thus include the effects of self-consistent electric and magnetic fields, magnetic induction, and electromagnetic radiation. The algorithms for an electromagnetic code which works directly with the electric and magnetic fields are described. The fields and current are separated into transverse and longitudinal components. The transverse $\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\thicksim}$}}{E} $ and $\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\thicksim}$}}{B} $ fields are integrated in time using a leapfrog scheme applied to the Fourier components. The particle pushing is performed via the relativistic Lorentz force equation for the particle momentum. As an example, simulation results are presented for the electron cyclotron maser instability which illustrate the importance of relativistic effects on the wave-particle resonance condition and on wave dispersion.
