Abstract

A new code for the calculation of low-frequency electromagnetic wave propagation in general three-dimensional plasma configurations is presented. The recent studies of E/M perturbations in 3D plasmas in the low frequency range (ICRF and shear Alfvén waves, both continuum part of the spectrum and discrete eigenmodes), potentially important for plasma heating, stability and current drive in stellarators, demonstrate a variety of models, approximations and numerical methods to solve the propagation problem. We are developing a code LEMan for modelling E/M wave propagation in inhomogeneous fully 3D plasmas of a finite spatial extent, including the effects of absorption of the incident wave, reflection from the walls, etc. No assumption on the wavelength is made.
