| Summary: | In this article we study a charge-conserving finite-element particle scheme for the
Maxwell-Vlasov system that is based on a div-conforming representation of the electric
field and we propose a high-order deposition algorithm for smooth particles with piecewise
polynomial shape. The numerical performances of the method are assessed with an academic
beam test-case, and it is shown that for an appropriate choice of the particle parameters
the efficiency of the resulting method overcomes that of similar finite-element schemes
using point particles. |
