摘要：

A single grating rectangular waveguide is used as the slow-wave structures (SWS) of 0.978THz BWO. The dispersion characteristics of single grating structure are studied by Matlab simulation, and the structure parameters of grating are obtained. On this basis, three-dimensional electromagnetic simulation software Magic was used to build the structure model for simulation. Finally, under the condition of 1KV voltage and 100A/cm(2) banded electron injection input, the electromagnetic wave with output frequency of 0.978THz and power of 3.9mW can be obtained with an efficiency of 0.65%.
