摘要
The mechanism of the avionics being interfered by the inside electromagnetic field through wires inductive coupling is discussed. This interference mode has both the radiation and transmission features. The theories and methodologies of aperture diffraction, field-to-wire excitation, transmission line with distributing voltage source, and circuit analysis are applied to establish the prediction model. The practical computer program is developed to evaluate the reliability and safety of avionics and electronic components.
