Abstract

The invention discloses a complementary split resonant ring slow-wave structure with miniaturization and high coupling impedance, which belongs to the technical fields of vacuum microwave electronics, accelerators, Cerenkov particle detectors and the like. The slow-wave structure includes a metal circular waveguide and a CSRR unit array filled along the axis inside it. The complementary split resonant ring has strong resonance characteristics, and any operating frequency can be achieved by changing the lateral size of the complementary split resonant ring. Compared with the traditional slow-wave structure of the same frequency band (S-band), the slow-wave structure of the present invention has a cross-sectional area of ​​only 1 / 8 to 1 / 9 of that of the traditional coupling cavity slow-wave structure of the same frequency band, and the coupling impedance is the same as that of the traditional slow-wave structure of the S-band. 2 to 4 times that of the coupled cavity slow-wave structure. Because the slow wave structure has the characteristics of miniaturization and high coupling impedance, the invention can be applied in the fields of miniaturization, high efficiency and high power linear vacuum injection electronic devices, accelerators and Cerenkov particle detectors.

Description

technical field [0001] The invention belongs to the technical fields of vacuum microwave electronic devices, accelerators and Cerenkov particle detectors, and in particular relates to a complementary split resonant ring slow-wave structure with miniaturization and high coupling impedance. Background technique [0002] Due to its unique advantages in power, efficiency, bandwidth and gain, vacuum electronic devices have become the core devices in the fields of accelerators, microwave heating, communications, radar, electronic warfare and high-power microwave weapons. As the most widely used vacuum electronic device, traveling wave tubes are widely used in aerospace, medical, industry and particle detection technology. As the core part of the TWT, the slow-wave structure directly determines the overall performance of the TWT, including operating bandwidth, electronic efficiency, gain, and output power. Traditional helical slow-wave structures and coupled-cavity slow-wave struc...
