等离子体的存在对强流相对论电子束驱动的微波器件的工作特性有很大的影响。用等离子体加载真空微波振荡器改变辐射的功率和频带。切伦科夫等离子体脉塞是一种内部只有等离子体的微波激射器，与真空器件相比，既有很大的优点，也有固有的缺点。此外，在高功率微波或电子通量的影响下，等离子体自发地出现在相对论微波振荡器中;这种寄生等离子体导致微波脉冲缩短，主要是在微秒范围内工作的设备中。本文综述了自1970年至今在相对论等离子体微波电子学方面进行的大量实验研究。
The presence of plasma affects drastically the operation of microwave devices driven by high-current relativistic electron beams. Loading vacuum microwave oscillators with plasma changes the power and frequency band of the radiation. The Cherenkov plasma maser, that operates only with plasma inside, has both promising advantages and inherent disadvantages comparatively to the vacuum devices. Besides, plasma appears in a relativistic microwave oscillator spontaneously under the influence of high-power microwaves or electron fluxes; this parasitic plasma causes microwave pulse shortening, mainly in devices operating in the microsecond regime. The large body of experimental research carried out in relativistic plasma microwave electronics since 1970 up to now is the subject of this review.
