Abstract:

An investigation was conducted into the microwave resonant absorption of ten energetic compounds over the frequency range from 2.5 to 18 GHz. The samples ranged in sensitivity from relatively inert liquid fuels to the most sensitive explosive initiators. Low power testing showed no strong frequency dependence for any of the materials tested. High power tests were conducted at an S-band frequency at power densities exceeding 1 kWsq cm. No detonation, deflagrations or decompositions were observed. As a result of these tests one can conclude that, for the materials tested and in the frequency range investigated, no susceptibility to direct high power microwave radiation exits for power density levels less than one kilowatt per centimeter squared.
