Abstract: The authors have applied a fully three-dimensional ray-tracing code to stellarators to examine the propagation of electromagnetic radiation near the electron cyclotron frequency in straight stellarators, toroidal stellarators, and tokamaks.^ The stellarators are simulated by using numerically computed vacuum magnetic fields and are assumed to have temperatures and densities which are constant on the flux surfaces.^ A comparison of the topology shows that, even for large aspect ratios, the 1/R B-dependence is the dominant effect on the location of the resonance and cutoff layers in the toroidal devices.^ Hence, straight stellarator geometry is not appropriate for ray-tracing purposes in this parameter regime.
