| Abstract: | The field emission properties of carbon nanotubes are excellent, therefore they are a promising source of electron emission. The emission mechanism of nano-materials are explored in this paper, the electromagnetic software CST is used for building simulation models, and appropriate simulation environment is developed according to the specific structural characteristics of the carbon nanotubes. The simulation results are of great importance to the study of using carbon nanotube array as field emission cathode microwave tube. |
