TITLE OF THE INVENTION: WAVEGUIDE FOR THE TRANSMISSION OF ELECTROMAGNETIC ENERGY ABSTRACT OF THE DISCLOSURE A waveguide For the transmission of electromagnetic energy which has a low attenuation even with a small line cross-section realized by disposing in the interior of an electromagnetically shielded hollow cylinder consisting of a substance having a low permittivity, a dielectric wire of a substance having a high permittivity. An EOm,-wave (m = 1, 2, 3,...., circular H field) is exci- ted in the dielectric wire and the dimensioning of the dielectric wire is such depending on the permittivities of the two substances and the particular op- erating frequency that a TEM wave develops at least substantially in the space in the dielectric hollow cylinder. In the simplest case, the electro- magnetic shield can consist of a metal tube and the dielectric hollow cylinder can consist primarily of air. Furthermore, the Eom wave excited in the die- lectric wire is preferably the Eo1 wave (TM01 mode).
