AB A two-dimensional, full-wave, frequency domain, coldplasma model is used to study electromagnetic powerpropagation and absorption in a helicon plasma thruster,including its far plume region and surrounding space. Re-sults show that a fraction of power is absorbed in theplume region, and that power deposition in the sourceis essentially unperturbed by the simulation domain size,the presence of metallic obstacles, or the plasma den-sity in the environment. An electron-cyclotron reso-nance (ECR) surface always exists downstream that ef-fectively prevents radiation to the space beyond alongthe plume. In the presence of an overdense environmen-tal plasma, like the one expected in a vacuum cham-ber, elds are fully evanescent beyond this transition,and vacuum chamber boundary conditions a ect but lit-tle the waveelds before this surface. In the absence of anenvironmental plasma, a double wave regime transitionexists at the interface between the plasma and vacuumthat hinders accurate numerical simulation in the plumeregion.
