摘要 本文概述了新型空间谐波磁控管（SHM）的理论、设计、仿真和制造。将提供近似分析，为设计提供指导并预测这些设备的重要特性。该分析表明，加载超材料的 SHM 可以在非常小的阴极电流密度下开始发电，这对于设计基于 SHM 的太赫兹源非常重要。将检查工作频率为 43 GHz 的设计示例以及设计过程、PIC 仿真和测量结果。
Abstract This paper provides an overview of theory, design, simulation, and fabrication of novel spatial harmonic magnetrons (SHMs). An approximate analysis which provides the guidelines for the design and predicts the important characteristics of these devices will be presented. This analysis shows that the metamaterial loaded SHMs can start generating power with very small cathode current densities which is very important for designing THz sources based on SHMs. A design example with the operation frequency of 43 GHz together with the design procedure, PIC simulations, and measurement results will be examined.
