Application of Jones matrices to the analysis of far-infrared wave propagation in tokamak plasmas
In this paper a method is developed to describe the change of polarisation of an electromagnetic wave traversing a non-uniform, magnetised plasma in terms of a 2 x 2 matrix. It is shown by model calculations that this transformation matrix yields the same results as those obtained by the well-established Poincaré sphere method. The formal equivalence of the plasma matrix to Jones matrices representing polarisation-sensitive optical components makes it possible to devise simple and versatile simulation programmes for real polarimetric instruments. As an example, the heterodyne polarimeter used on the TEXTOR tokamak is discussed.
