利用调频脉冲在色散介质中的被动压缩现象，将微波峰值功率提高到千兆瓦级。一个螺旋波纹波导被用作DM，而相对论X波段返波振荡器（RBWO）与下降期间的脉冲加速电压作为FM脉冲源。压缩的脉冲下降到2.2纳秒的半宽度伴随着4.5倍的功率增加到约3.2 GW的值已被证明。
The phenomenon of passive compression of frequency-modulated (FM) pulses in a dispersive media (DM) was used to increase the peak microwave power up to the multigigawatt level. A helically corrugated waveguide was used as the DM, while a relativistic X-band backward-wave oscillator (RBWO) with a descending-during-the-pulse accelerating voltage served as a source of FM pulses. Compression of pulses down to a halfwidth of 2.2 ns accompanied by a 4.5-fold power increase up to a value of about 3.2 GW has been demonstrated.
