The spectrum of the waves of a circular open dielectric waveguide, including the frequency sections corresponding to leaky waves, complex and slow improper waves, has been considered. The power flux density for these waves has been calculated. Analysis of the distribution of the real part of the power flux density along the radial coordinate has been carried out.
The results of the calculation of the radial component of the Umov–Poynting vector, which may be called the flux density of radiation power, are given for the EH11 wave at different frequency points of the dispersion characteristic.
The investigation of the distributions of the normalized real part of the radiation power flux density along the radial coordinate for the waves of a circular open dielectric waveguide has shown that it is most effective to use segments of a circular open dielectric waveguide as emitters either on symmetric outflow waves in the entire range of their existence, or on an evolving EH11 wave, where it has a normal dispersion.
