Abstract:
      A field-line coupling model of twisted pair was theoretically investigated. The external electromagnetic pulse (EMP) and twisted pair model were established. The terminal response of twisted pair under EMP excitation in frequency domain was studied. Based on transmission line theory, the field-line coupling model of twisted pair was used for calculating the interference coupling response of twisted pair under strong EMP incident. Coupling terminal current of twisted pair with different terminal impedance was analyzed.
