Abstract
A slow-wave circuit is provided with a folded waveguide and a beam hole. The beam hole is arranged between an edge and a center in the direction of width of the folded waveguide. The beam hole is preferably arranged at an edge in the direction of width of the folded waveguide, at a position that does not protrude beyond the folded waveguide. The beam hole is preferably arranged at a position separated by a prescribed distance from the edge in the direction of width of the folded waveguide.
Claims7
A slow-wave circuit, comprising:
- a folded waveguide, and
- a beam hole, which is the total area of a path of an electron beam in the folded waveguide, is arranged between an edge and a center in a direction of width of said folded waveguide, the direction of width being perpendicular to a traveling direction of an electromagnetic wave and being perpendicular to a height direction of the folded waveguide, the height direction extending from a bottom of the folded waveguide to a top of the folded waveguide, the top of the folded waveguide including a fold of the folded waveguide.
