INFLUENCE OF LOCAL DISPERSION ON TRANSIENT PROCESSES ACCOMPANYING THEGENERATION OF RF RADIATION BY AN ELECTROMAGNETIC SHOCK-WAVE

Transient processes accompanying the conversion of a video pulse into a radio pulse in a nonlinear transmission line having hysteretic prope rties are studied. It is established that the transition process leadi ng to the establishment of ''steady-state'' (close in amplitude) oscil lations has a minimum when the electromagnetic shock wave front is pha se-matched with the wave excited by it at a frequency near the minimum local dispersion of the group velocity.
