Abstract: Aiming at improving the radiation direction of the radiating high altitude nuclear electromagnetic pulse(NEMP) simulator, Transverse electromagnetic(TEM) horn antenna is adopted as the radiating antenna for the simulator in this paper. Several structures are simulated using the CST microwave studios software. Results suggest that TEM horn antenna can be used by NEMP simulators with some limitations; the near field waveform is closer to standard waveform than far field one; the structures of impedance loading and low frequency compensation have limited effect on improving the antenna's radiation performance; the other two structures of impedance with gradually exponential changing and edges rolling can perfect the radiation waveforms greatly. © 2017 Applied Computational Electromagnetics Society.

Abstract: Field-induced electromagnetic shielding material show an abrupt decrease of resistance when external electromagnetic field exceeds a threshold value, the material will occur metal-insulator transition phenomena in the nanosecond time, Owing to threshold value was so high that traditional static test method and low-voltage dynamic test can not satisfy test require. According impedance matching principle and time domin reflection, two kinds of dynamic test device are designed, the working principle of them are compared and analyed, pulsed measurement show that the test device based on time domin relection is more correct and directly. © 2017 Applied Computational Electromagnetics Society.
