A novel H-plane loaded on a double-staggered grating waveguide (DSGW) slow-wave structure (SWS) is proposed. The main advantage of this SWS is its high interaction impedance and low phase velocity, based on which higher output power can be expected. Electromagnetic characteristics and particle-in-cell simulations were performed using CST Microwave Studio software. The dispersion diagram of the SWS was optimized for a central frequency of 94 GHz which corresponds to a beam voltage of 13.2 kV in the second spatial harmonic (2\(\pi\)–3\(\pi\)). A sheet electron beam with a current of 200 mA is used to interact with the longitudinal electric field. The reflection signal at the input port is below −15 dB for frequencies of 89–98 GHz and a small-signal gain of 35 dB is achieved at the output port for a tube length of 80 mm.

提出了一种新型的H平面加载在双交错光栅波导（DSGW）慢波结构（SWS）上。该SWS的主要优点是其高的相互作用阻抗和低的相速度，据此可以期望更高的输出功率。使用CST Microwave Studio软件进行电磁特性和细胞内颗粒模拟。SWS的色散图针对94 GHz的中心频率进行了优化，该中心频率对应于二次空间谐波（2 \（\ pi \） –3 \（\ pi \）中的13.2 kV光束电压）。电流为200 mA的薄电子束用于与纵向电场相互作用。对于89–98 GHz的频率，输入端口的反射信号低于-15 dB，对于80 mm的管长，输出端口的反射信号增益为35 dB。
