本文综述了目前无源高功率微波元件在射频等离子体产生和加热、等离子体诊断、等离子体和微波材料加工、光谱学、通信、雷达测距和成像以及下一代高场梯度电子-正电子线性对撞机驱动器中的应用。本文介绍了光滑壁波导、HE/sub - 11/混合模波导和准光学TEM/sub - 00/光束波导等用于超模高功率传输系统的大功率元件。这些包括各种类型的模式转换器，偏振器，截面圆锥，弯曲，模式选择滤波器，脉冲压缩机，直流断路器，定向耦合器，光束合并器和分频器，真空窗和模式分析仪器。详细讨论了欧姆衰减和不必要的寄生模式转换问题，并给出了对准要求的规则。在波导传输的情况下，本文主要集中于圆波导元件，但也涉及矩形波导。
This review discusses the present state-of-the-art of passive high-power microwave components for applications in microwave systems for RF plasma generation and heating, plasma diagnostics, plasma and microwave materials processing, spectroscopy, communication, radar ranging and imaging, and for drivers of next generation high-field-gradient electron-positron linear colliders. The paper reports on high-power components for overmoded high-power transmission systems such as smooth-wall waveguides, HE/sub 11/ hybrid mode waveguides and quasi-optical TEM/sub 00/ beam waveguides. These include various types of mode converters, polarizers, cross-section tapers, bends, mode selective filters, pulse compressors, DC-breaks, directional couplers, beam combiners and dividers, vacuum windows, and instruments for mode analysis. Problems of ohmic attenuation and unwanted conversion to parasitic modes are discussed in detail and rules for alignment requirements are given. In the case of waveguide transmission, this review mainly concentrates on circular waveguide components but also deals with rectangular waveguide.
