Embodiment 1
[0022] Embodiment 1: The planar slow-wave structure adopts a rectangular double-grid slow-wave structure. According to the parameters of the rectangular double-grid, the height of the energy output structure is 4mm and the width is 46mm. Through calculation, a circular arc transition (with a radius of 4 mm) is adopted, and the angle between the energy output structure and the slow wave structure is 45 degrees. The electron beam interacts with the rectangular double-gate structure to generate high-power millimeter wave oscillation, and then the TE wave is output from the energy output structure. The whole device generates high power oscillation output at 36GHz such as Figure 5 shown (measured at image 3 far left of the energy output structure shown).
Embodiment 2
[0023] Example 2: The slow-wave structure adopts a sinusoidal waveguide grating (single-grid or double-grid) slow-wave structure, and other structures remain unchanged. Through optimal design, the angle between the rectangular oblique waveguide 2 and the planar sinusoidal waveguide grating slow-wave structure 1 is 30 degrees, the output energy is output along the rectangular straight waveguide 3 .
Embodiment 3
[0024] Embodiment 3: The slow wave structure adopts the trapezoidal grid (single grid or double grid) slow wave structure, and other structures remain unchanged. Through optimized design, the angle between the rectangular inclined waveguide 2 and the flat trapezoidal grid slow wave structure is 60 degrees. The output energy is output along the rectangular straight waveguide 3 .
