Abstract : A demonstration is presented of the derivation of ray equations for inhomogeneous anisotropic media by use of variational calculus. These equations are then adapted to the case of ionospheric propagation. To demonstrate validity of these equations a comparison is made of these and others derived by use of a vector method. Although these latter equations have been demonstrated usable, for example, to study ray paths of radio transmissions from a rocket to a ground receiving station, they are not in the form desired for use with an analog computer. The equations derived here would be more easily adapted to that end. (Author)
