Abstract :
The essence of the offered mechanism consists of the following: during expansion of products of detonation a highly non-equilibrium medium is generated, the oscillatory temperature of which can essentially exceed the rotational one. Such a medium is basically active from the point of view of generation and amplification of microwave radiation. As against laser active media, the frequency of collision of molecules is about the frequency of radiation, therefore the radiation will be wideband. As the air behind a shock wave is strongly ionized, the radiation can leave the explosion zone boundaries only after the decrease of this ionization because of its expansion and instability of border of detonation products. Presence of a shell as a way of initiation of the charge can accelerate process of destruction of a conducting layer behind a shock wave
