Evolution of Particle-in-Cell Plasma Simulation

IEEE Transactions on Plasma Science, 2013
Particle-in-Cell (PIC) methods first made it feasible to simulate plasmas and microwave devices in two dimensions on 1960's computers. In this approach, the electromagnetic interactions between charged particles are mediated by a spatial mesh, on which currents and field are defined.

Particle‐in‐Cell Simulations for Ion Thrusters

Contributions to Plasma Physics, 2009
AbstractThe Particle‐in‐Cell (PIC) method was used to study two different ion thruster concepts: Hall Effect Thrusters (HETs) and High Efficiency Multistage Plasma Thrusters (HEMPs), in particular the plasma properties in the discharge chamber due to the different magnetic field configurations.

Particle-in-cell simulation method for macroscopic degenerate plasmas

Physical Review E, 2020
Nowadays hydrodynamic equations coupled with external equation of states provided by quantum mechanical calculations is a widely used approach for simulations of macroscopic degenerate plasmas. Although such an approach is proven to be efficient and shows many good features, especially for large scale simulations, it encounters intrinsic challenges ...

Multi-scale particle-in-cell plasma simulation

Journal of Computational Physics, 1990
Abstract We describe a form of self-consistent particle-in-cell plasma simulation which is applicable to strongly inhomogeneous systems involving a wide range of space and time scales. In this multi-scale method, the plasma particles in each region of phase space are advanced using a step size appropriate to that region, as determined by accuracy ...

Particle-in-cell simulations of magnetosphere electrodynamics

IEEE Transactions on Plasma Science, 2000
This paper reviews the basic principles and techniques involved in formulating particle-in-cell (PIC) simulation models which can be used to address medium- and large-scale problems in magnetosphere electrodynamics. The limitations imposed by the underlying kinetic physics of a plasma are emphasized, and representative algorithms are described for full

Electrostatic Particle-in-Cell Simulation Technique for Quasineutral Plasma

Journal of Computational Physics, 1997
The authors develop a simulation method for a quasineutral plasma with electrons and ions taken as particles-in-cell. The electrostatic field is determined from the neutrality condition which enables a better self-consistent calculation of the potential. The method correctly represents features like the ion and electron Landau damping and is applied to

Particle-in-cell simulation of ion Bernstein wave excitation

Physics of Plasmas, 2002
Ion Bernstein wave excitation is investigated with the self-consistent two-dimensional particle-in-cell method. The real ion to electron mass ratio is used in simulations in high harmonic frequency bands. The simulation results are compared with linear theory and ray tracing.

Particle‐In‐Cell Simulations of Starfish Prime

Journal of Geophysical Research: Space Physics
AbstractThe Starfish Prime high altitude nuclear test created a transient diamagnetic cavity in the Earth's magnetic field above Johnston Island and launched an electromagnetic pulse (EMP) that was detected around the globe. We use the ion‐kinetic particle‐in‐cell code Topanga to simulate diamagnetic cavity evolution and the E3 EMP signal for Starfish ...
