HPM (high-power microwave) weapons become the major threat to individual equipment which is developing to be unmanned and intelligent. A typical inertial device of individual equipment is taken as the research object to find out its coupling paths based on the analysis of function and structural characteristics, and the effects of HPM coupling to the typical inertial device are simulated by the numerical simulation software CST. The results shows that power and signal cables of MEMS (Micro-Electro-Mechanical System) accelerometer are the main coupling paths of HPM; The power cable has size coupling effect which is strongest when the sum of the cable length and twice the distance to the “ground” is equal to odd times of quarter wavelength, and weakest when the cable length is equal to even times of quarter wavelength; The signal cable has wavelength coupling effect that is positively correlated with cable length which is less than wavelength, and not affected by cable length which is greater than wavelength; The screen in signal cable not only greatly reduces the peak value of coupling voltage, but also effectively reduces the influence of cable length on the coupling effect. The research results provide support for the protection of individual inertial devices, and also provide a reference for the design of HPM weapons.

“…Therefore, for a safe and stable operation of the electrical power systems, we should evaluate, analyze and predict the antijamming capability of electrical power system and relay protection equipments in strong electromagnetic interference environment, thereby make some necessary strengthening and protection, which is of important in the theoretical and practical significance. Among those experiments, the effects and the electromagnetic pulse coupled topology under the repetition pulses, especially for the fast transient electromagnetic pulse with the interval of tens of µs, has been an interesting issue for researching [1][2][3][4][5]. In fact, compared with the single pulse, the high repetition pulses are closer to actual electromagnetic pulse, like the repetition of nature lightning, a variety of over-voltage in the industrial power distribution, e.g.. Techniques of high-repetition-rate experiments mainly include the following aspects: the technology to generate repetition pulses with high power, technology for the simulation of electromagnetic radiation field and the measurement and calculation of electromagnetic field, in which the technology to generate the repetition pulses with high power is most critical.…”

Repetition pulses with sub-microsecond arising time, high voltage and large current, have been widely utilized in the field of production and scientific research, in which the gas spark switch is usually selected because of the large state current and the high operating voltage. However, due to the recovery property of gas ionization, it is hard to get the repeated switch-on and switch-off at a high rate towards the conventional gas spark switch. Owing to the reliably triggering and faster arising time, the hydrogen thyratron is found to be more suitable for the switch to generate the repetition pulses at a high rate. In this paper we proposed a novel design of repetition pulses, in which it gets a several times high voltage output based on the inductive-adder, by using the hydrogen thyratron switch with a low operating voltage, and then we analyze the magnetic field distribution under the structure of the coaxial cable and describe the design of high voltage repetition pulses in details
