提出了一种由赝火花源片状电子束（SEB）驱动的太赫兹双模扩展相互作用振荡器（EIO）。新开发电路的主要优点包括 1) 高密度 SEB 分别与 TM11 和 TM31 模式相互作用，2) 在亚太赫兹频率范围内输出功率超过 1 kW。研究了两种不同类型的2π模式及其输出特性，并对电路进行了优化，保证了两种驻波模式的高效输出。三维 (3D) 颗粒细胞 (PIC) 仿真预测，在 TM11 模式下工作时，最大输出功率为 1.3 kW，303 GHz 时的 3 dB 带宽约为 0.5 GHz，而在 TM31 模式下，364 GHz 时的最大输出功率为 3.18 kW，364 GHz 时的 3 dB 带宽约为 0.85 GHz。
A terahertz dual-mode extended interaction oscillator (EIO) driven by a pseudospark-sourced sheet electron beam (SEB) was presented. The major advantages of the newly developed circuit include 1) high-density SEB interacting with the TM11and TM31modes, respectively, and 2) high output power of over 1 kW at the sub-terahertz frequency range. Two different types of 2πmodes and their output characteristics were studied, and the circuit was optimized to ensure efficient outputs of two standing-wave modes. The three-dimensional (3D) particle-in-cell (PIC) simulation predicts the maximum output power of 1.3 kW with a 3-dB bandwidth of ~0.5 GHz at 303 GHz when operating at the TM11mode, and 3.18 kW, 3-dB bandwidth of ~0.85 GHz at 364 GHz when operating at the TM31mode.
