Wideband chaotic generation in K-band helical waveguide gyro-TWT with external reflections

Abstract

Results of simulations of wideband chaotic generation based on a helical waveguide K-band gyro-TWT with external reflections are presented. It is shown that as the reflection coefficient increases, a spectrum width of about 2 GHz is achieved in the system. For experiments a broadband Bragg-type reflector with a non-uniform corrugation period and depth, providing the necessary reflections in the frequency range 23–25 GHz was fabricated.
