Schneider Física, Astronomía y Matemáticas The procedures used to obtain general expressions for the components of the effective dielectric tensor for electromagneticwaves in inhomogeneous magnetized plasmas are briefly reviewed, and the relationship betweenthese expressions and their counterparts which can be obtained assuming electrostatic fluctuations is discussed.It is argued that a general formulation formerly available in the literature, which do not satisfy Onsager symmetryin the case of electrostatic fluctuations, is not the suitable form for description of dielectric properties in theelectrostatic case, which require a dielectric constant.
