During the 20 years in which two-dimensional electromagnetic particle-in-cell codes have been in intensive use, discussion has continued as to how best to honor both the Ampere-Maxwell equation and Gauss' law in spite of compromises made in the collection of the density and current terms from the pa

The aim of this paper is to present a new explicit time scheme for electromagnetic particle simulations. The main property of this new scheme, which depends on a parameter, is to reduce and in some cases to suppress numerical instabilities that can appear in this context and are widely described in
rates on the electron time scale. If the electron time scale is the fastest time scale of the system, it is then appropriate A hybrid particle-in-cell (PIC) method is presented in which the electrons are modeled as an adiabatic fluid with an arbitrary ratio to use the time-explicit PIC algorithms b
