To address the aforementioned research gap, this paper aims to design a novel ridge-dielectric composite loaded folded waveguide slow-wave structure for W-band traveling-wave tubes. A composite collaborative optimization scheme of ridge loading and dielectric loading is proposed for the first time, which breaks through the inherent bandwidth-impedance contradiction of traditional structures. Specifically, the electromagnetic simulation model is established, the influence mechanism of key parameters is analyzed, the optimal structural parameters are determined, and the sample is fabricated and verified by cold test and hot test. The rest of this paper is organized as follows. Section 2 introduces theoretical analysis and simulation setup. Section 3 presents parametric optimization results. Section 4 provides experimental verification. Section 5 summarizes conclusions and prospects.

七、Introduction 时态语态铁律（和 Methods/Abstract 完全统一）
- 领域现状、前人研究、客观真理→一般现在时
- 本文工作、提出、设计、实验、分析→一般过去时
- 创新点、结论、价值→一般现在时
- 文献引用被动语态优先，避免一句一句堆作者。
八、Introduction5 大高频避坑
- 不写成文献综述，只评述不堆砌
- 缺口必须和创新一一对应
- 语气委婉客观，不尖锐贬低前人
- 漏斗从宽到窄，不发散跑题
- 创新点具体量化，不模糊空话
系列结尾总结
