Dielectric-in-cell and N-body-dielectric simulations of E→ x B→ drifting plasma clouds

Two computational methods for simulating E→ x B→ drifting plasma clouds are demonstrated. Both methods involve representing the plasma cloud by a large number of dielectric elements, each of which E→ x B→ drifts in a local electric field. This local electric field is the sum of an externally imposed uniform electric field and a polarization electric field. The local value of the polarization electric field depends on the configuration of the entire plasma cloud, hence it depends on the location of all of the dielectric elements that make up the cloud
