Methods for Free-Space Ultra-Short Solitary EMP Measurement
There are some suitable methods for ultra-short solitary electromagnetic pulses (EMP) measurement. The EMPs are generated by high power microwave generators. The characteristic of EMPs is high power level (Pmax = 250 MW) and very short time duration (tp Î <1, 60> ns). Special requireme...

| Summary: | There are some suitable methods for ultra-short solitary electromagnetic pulses (EMP) measurement. The EMPs are generated by high power microwave generators. The characteristic of EMPs is high power level (Pmax = 250 MW) and very short time duration (tp Î <1, 60> ns). Special requirements for measurement methods are placed because of the specific EMPs properties.Two suitable methods for this application are presented in the paper. The first – calorimetric method, utilizes the thermal impacts of microwave absorption. The second method presented – magneto-optic method, use the Faraday’s magneto-optic effect as a sensor principle. It was realized combined calorimetric sensor and there were made some experimental EMP measurements with good results. The sensor utilizing magneto-optic method is in development. |
