A Full-Wave Solution of the Maxwell's Equations in 3D Plasmas

We present a new global solver for the Maxwell's equations in stellarator plasmas (LEMan). The 3D geometrical effects are fully taken into account, no assumption on the wavelength is made. The full cold plasma dielectric tensor including finite electron mass is implemented, extension to the kinetic model is under development. The wave equation is discretised with finite elements (linear or cubic) radially and Fourier decomposition in the poloidal and toroidal angles. Special care is taken to correctly treat the problem near the magnetic axis. Unicity of the solution, gauge condition and the energy conservation are ensured. Some results and benchmarks for the Alfven and ion cyclotron frequency ranges are presented
