THE MODEL OF PULSE RADIATOR WITH OUTPUT SIGNAL COMPRESSION IN HELICALLY COILED DIELECTRIC WAVEGUIDE
RÉSUMÉ
Rigorous simulation of electromagnetic pulse compression induced by a filament of external current in a helically coiled segment of dielectric waveguide is performed. The width of the pulse spectral band is around two octaves, it ranges from 1.4 to 5.7 GHz. An 8-time compression of pulse duration has been obtained with dielectric waveguide length is just over than 2.5 m. The duration of output signal is 2 ns. The Time reversal method has been used for finding the time profile of the current pulse. It permits us to compensate (by an external source) the energy loss of the pulse under compression during its propagation along the waveguide and radiation into open space.
