Abstract :
A re-entrant cavity resonator with carbon nanotubes cold cathode was fabricated. The cold cathode was driven by L band signal and a modulated electron emission of CNTs was achieved. An average current of 3.865 μA was recorded when a 1W/1.572GHz signal was led in the cavity, corresponding density of 193.3 μA/cm2. The highest output power was obtained at nearly 1.6S A re-entrant cavity resonator with carbon nanotubes cold cathode was fabricated. The cold cathode was driven by L band signal and a modulated electron emission of CNTs was achieved. An average current of 3.865 μA was recorded when a 1W/1.572GHz signal was led in the cavity, corresponding density of 193.3 μA/cm2. The highest output power was obtained at nearly 1.65 GHz frequency under 100 mW input.GHz frequency under 100 mW input.
