It must be self-contained, without references, abbreviations or unexplained terms.—— IEEE Transactions on Electron Devices 作者指南先看正反案例对比最直观场景反面教材口语化无重点不规范正面范例用本文句式优化背景 缺口Millimeter-wave traveling-wave tubes are very important. Many people have studied them, but they have some problems.Millimeter-wave traveling-wave tubes (TWTs) are the core power source for 5G/6G millimeter-wave communication and radar systems. However, the traditional folded waveguide slow-wave structures face the contradiction between wide bandwidth and high coupling impedance in the W-band, which limits the further improvement of the devices power and efficiency.创新 结果We made a new structure, did some simulation and test, and got good results.To solve this problem, we proposed a ridge-loaded folded waveguide slow-wave structure for the first time. The electromagnetic simulation and cold test results show that the proposed structure achieves a 35% relative bandwidth in the W-band, and the coupling impedance is increased by 22% compared with the traditional structure.价值Our work is useful for the design of TWTs.The proposed structure provides a new solution for the design of high-efficiency wideband W-band TWTs, and has broad application prospects in millimeter-wave wireless communication systems.二、场景 1研究背景与领域重要性 ——8 个黄金句式告别空洞开头一秒立住研究价值核心说明这是摘要的开头第一句核心是 **“从大到小” 聚焦 **从宏观领域的重要性落到你研究的细分方向的必要性不能上来就写细节也不能空洞喊口号。核心句式清单附使用说明句式编号学术句式可直接套用适用场景①[研究领域] is/are the core/key/indispensable technology/component for [核心应用场景], and has/have attracted extensive attention in the field of [细分领域].宏观领域重要性总述通用万能开头②With the rapid development of [行业 / 技术e.g., 6G millimeter-wave communication], the demand for [研究对象e.g., high-power millimeter-wave radiation sources] is increasing rapidly.技术发展驱动的研究背景贴合行业需求③[研究对象] has/have been widely used in [高端应用场景e.g., space-borne radar, satellite communication] due to its/their outstanding advantages of [核心优势e.g., high power, wide bandwidth].基于研究对象优势的背景说明工科通用④In recent years, [研究方向] has become a research hotspot in the field of [领域], as it can effectively solve the pain point of [现有技术的核心问题].热点研究方向背景说明突出研究的时效性⑤The performance of [核心系统e.g., millimeter-wave radar system] is largely determined by the [核心器件 / 技术e.g., power amplifier], which has become the key bottleneck restricting the development of the system.从系统瓶颈切入突出细分研究的必要性⑥High requirements have been put forward for [研究对象] in terms of [性能指标 1], [性能指标 2] and [性能指标 3] with the development of [应用场景].面向应用需求的指标要求突出研究的针对性⑦[技术 / 器件] plays a critical role in [前沿领域e.g., terahertz imaging, deep space communication], and has become the focus of current research.前沿领域研究背景适合顶刊论文⑧Despite the great progress made in [现有研究方向], there are still great challenges in [细分场景] to meet the requirements of [应用需求].背景收尾自然过渡到研究缺口承上启下实战示例结合微波电子管论文场景Millimeter-wave traveling-wave tubes (TWTs) are the core power amplifiers for 6G millimeter-wave communication and high-resolution radar systems, and have attracted extensive attention in the field of vacuum electronics.With the rapid development of W-band wireless communication technology, the demand for wideband, high-efficiency millimeter-wave TWTs is increasing rapidly. The performance of the W-band TWT is largely determined by the slow-wave structure, which has become the key bottleneck restricting the improvement of the devices bandwidth and efficiency.Despite the great progress made in folded waveguide slow-wave structures, there are still great challenges in balancing the bandwidth and coupling impedance in the W-band to meet the requirements of high-efficiency wideband applications.图文对应看图学用法图片里的「1.

Compared with the traditional folded waveguide structure, the proposed scheme achieves a wider relative bandwidth and higher coupling impedance, and the processing difficulty does not increase significantly.We established a three-dimensional electromagnetic simulation model of the proposed structure, and systematically analyzed the influence of ridge height, dielectric layer thickness and other key parameters on the high-frequency characteristics of the slow-wave structure. On this basis, we designed and fabricated the slow-wave structure sample, and carried out cold test and whole-tube hot test verification.图文对应图片里的「3.
