Electromagnetic interference effects in the bipolar voltage comparator was investigated in this paper. By using of bulk current injection (BCI), the coupling current stimulated by high power electromagnetic pulse was simulated. The experimental results shown that the aberrations such as pulse deriving and pulse width altering will come into being in the output waveforms of LM139 after current injection respectively. Furthermore, the coupling effect of pulse deriving and pulse width broadening were observed simultaneously in the higher level current injections.

“…Electromagnetic pulse (EMP) produced by nuclear explosion, lighting and electrostatic discharge can disrupt or damage critical electronic facilities over an very large area, so it usually act as a killer of unprotected electrical and electronic equipment [1]. In order to research the action mechanism of the EMP and the characteristic of the transient electromagnetic field, the time domain measurement theory and technologies of transient electromagnetic field has become one of the focal point in the region of EMP attack and protection.…”

“…Because of steep rising front edge, short duration time and wide spectrum, transient electromagnetic pulse (EMP) can easily couple into the internal structure of missiles or aircrafts through apertures and slots [1]. Lots of essential openings in the shell of targets, such as hot-radiating windows and data openings, provide the coupling path for transient EMP.…”

Abstract-Transient electromagnetic pulse (EMP) can easily couple into equipments through small apertures in its shells. To study the coupling effects of transient Gauss pulse to a cubic cavity with openings, coupling course is simulated using sub-gridding finite difference in time domain (FDTD) algorithm in this paper. A new grid partition approach is provided to simulate each kind of apertures with complex shapes. With this approach, the whole calculation space is modeled, and six kinds of aperture with different shapes are simulated. Coupling course is simulate in the whole time domain using sub-gridding FDTD approach. Selecting apertures with dimension of several millimeters to research, coupled electric field waveform, power density and coupling coefficient are calculated. The affect on coupling effects by varied incident angle and varied pulse width are also analyzed. The main conclusion includes interior resonance phenomenon, increase effect around rectangle aperture and several distributing rules of coupled electric field in the cavity. The correctness of these results is validated by comparing with other scholars' results. These numerical results can help us to understand coupling mechanism of the transient Gauss pulse.
