A planar microwave energy transmission window

Abstract

The invention discloses a planar microwave energy transmission window. Different from the traditional cylindrical window, the window is designed to be flat, and its height (thickness) is consistent with the height of the broad side of the waveguide, and remains unchanged. The middle size of the narrow side of the waveguide is larger than the size of both ends, and the window is loaded in the middle of the narrow side of the waveguide, so that the height corresponding to the vacuum window and the wide side of the waveguide remains unchanged, and only changes in the direction of the narrow side, so that the microwave energy transmission The window is flat, that is, the 2-D structure with constant width side height greatly saves space and is more conducive to integrated applications. In addition, it avoids the cumbersome process in the assembly process of the traditional microwave energy transmission window and the slow-wave structure, and facilitates integration with the slow-wave structure; the loading space reserved for the flat window becomes larger, which is beneficial to the processing of the window in the extremely high frequency band.

Description

technical field [0001] The invention belongs to the field of microwave electric vacuum technology, and more specifically relates to an energy transmission structure of an electric vacuum device, that is, a planar microwave energy transmission window. Background technique [0002] In the microwave transmission systems of various microwave electron tubes, electron linear accelerators, electron-positron colliders, spallation neutron sources, plasma heating devices, etc., various microwave energy transmission windows are widely used, and their functions are mainly to separate The high vacuum environment and atmospheric environment inside and outside the tube play the role of isolation between the inside and outside, ensuring the internal vacuum environment, and at the same time transmitting microwave power with the lowest possible loss. The performance of the microwave energy transmission window structure directly affects the bandwidth, power, reliability and life of microwave e...
