Abstract
This paper considers of a coordinate-free approach to wave propagation in anisotropic media. Based on the direct manipulation of vectors, dyadics, and their invariants, the approach eliminates the use of coordinate systems. It facilitates solutions and provides results in a greater generality. The paper contains the following results in coordinate-free forms: The formulation of eigenvalue problems, the dispersion equation, the polarization of waves in magnetic crystals, and the determination of the directions of field vectors.
