Abstract :
In this paper, the attenuation characteristics (attenuation vs microwave pulse power) of the microwave attenuator with wedge-type carbonyl iron (CI) under high power microwave (HPM) pulses are investigated. A reliable experimental platform was set up and used to measure the attenuation under HPM pulses. A database describing the attenuation dependence of the injected microwave pulse power (MPP) up to 100kW on various pulses width of 200ns to 1us and repeating frequency of 10Hz to 500Hz is created. The results indicate that (I) the attenuation decrease with the increasing of the injected MPP; (II) with the attenuation increasing, the variation of attenuation in whole injected MPP range increase; (III) the effects of different pulses width and repeating frequency on attenuation characteristics can be ignored.
