Adding Linear Kinetic Effects to Existing Finite-Difference Simulations

We present the proof-of-principle KINETIC-J module for iterative addition of all-order kinetic effects (parallel and perpendicular) in both the IC and EC frequency ranges, to any existing FD or FE frequency-domain full-wave RF simulation. The module calculates the linear, kinetic plasma current, such that given f(0) (r, v) and the cold plasma solution as an initial guess at the wave electric field, iterating the KINETIC-J module and the existing code (its internal plasma current replaced with the output of the module) converges to the kinetic solution. Since KINETIC-J does not use the k-space representation of the hot plasma dielectric, in favor of data parallel numeric integrals, implementing the module requires minimal code changes.
