Nonlinear electromagnetic formulation for particle-in-cell simulation of lower hybrid waves in toroidal geometry

Electromagnetic formulation of global gyrokinetic particle simulation in toroidal geometry

The fluid-kinetic hybrid electron model for global electromagnetic gyrokinetic particle simulations has been formulated in toroidal geometry using magnetic coordinates, providing the capabilities to describe low frequency processes in electromagnetic turbulence with electron dynamics. In the limit of long wavelength and no parallel electric field our equations reduce to the ideal magnetohydrody...

Electromagnetic particle simulation of the linear mode conversion and the nonlinear parametric decay instability of lower hybrid waves in tokamaks

In plasma simulations where the speed of light times a characteristic length is at a much higher frequency than the relevant parameters in the system, such as the plasma frequency, implicit methods begin to play an important role in generating e cient solutions in these multi-scale problems. Under conditions of scale separation, one can rescale Maxwell’s equations in such a way as to give a mag...

Full wave simulations of lower hybrid waves in toroidal geometry with Non-Maxwelian electrons

Analysis of the propagation of waves in the lower hybrid range of frequencies in the past has been done using ray tracing and the WKB approximation. Advances in algorithms and the availability of massively parallel computer architectures has permitted the solving of the Maxwell-Vlasov system for wave propagation directly [Wright et al., Phys. Plasmas (2004), 11, 2473-2479]. These simulations ha...
