W. Thimms are a source of high frequency radiation that is often irrelevant to the physics of interest. Unfortunately, a numerical CFL stability limit prevents either making c infinite or Δt large while using the usual explicit Maxwell’s equations for the fields. A modification of Maxwell’s equations, which

Nessim Sibonyagnitude and hardware development affects the feasibility. Gridless and Fokker-Planck codes are possible in 1D, but one needs grids and PIC codes in 2D and 3D. This imposes limits on Debye lengths, particle size and spacing, and on resolution. Nonspectral (local) E-M codes also suffer a Courant rest
