High Power Microwaves from a Non-Isochronic Reflecting Electron System (NIRES).

摘要

High-power microwave radiation of frequency 11 GHz and 36 HGz is observed when a 300 kV positive pulse is applied to an aluminized mylar anode of a reflex triode. The frequency of radiation varies as (square root of V)/(d to the n-th power), where V is the anode voltage, d the anode-cathode spacing and 0 < n < 1. The basic features of the radiation are explained by a theoretical model based on the energy dependence of the electron oscillation frequency.
