Abstract

The singularities of an asymptotic representation of electromagnetic fields radiated in magnetoactive plasma with the parameters of the near-Earth ionosphere in the range of helical waves are investigated. The singular points of the dispersion surface of the refractive index of electromagnetic waves in the aforementioned range are determined. At these points, asymptotic representations are obtained for the intensity and power of the radiated electric field. The dependences of the directions of the vectors of the electromagnetic-wave group velocities on the directions of the wave phase velocities are found in the entire range of helical waves.
