Transportation of unipolar electromagnetic pulses in a coaxial waveguide

The possibility of efficient passage of a unipolar pulse through a coaxial waveguide has been confirmed. During the demonstration experiment, it was shown that when the potential is excited on the waveguide plates by short pulses, the unipolarity of the pulses passing through the cable is maintained. The problem of the passage of a field of a uniformly moving charge through a waveguide is numerically simulated. It is shown that the main wave passes through the coaxial waveguide almost without loss. The pulse area remains non-zero not only inside the coaxial waveguide, but also near the outer boundary of the ideal waveguide.
