The field switching properties of NbO2/NbO, NbO2/(reduced NbO2) and polycrystalline nonstoichiometric NBO2 have been investigated. Under an applied electric field they switch from a high (greater than 10,000 ohms) to a low (apporximately 10 ohms) resistance in times smaller than 0.7 ns. For pulse durations of several nsec, the current carrying capability is higher than 80 A. the switching mechanism appears to proceed in two stages which could be electrode ...
The requirement for suppression of RF energy in ordnance ignition circuits may be stated in terms of the insertion loss of the network, which, inserted between the source (the equivalent generator) and the load (the resistance of the electro-explosive device, or EED), will limit RF energy at the EED to the tolerable level. The optimum theoretical treatment of RF suppression deals with the minimum of parameters and involves the minimum ...
