To characterize the shielding effectiveness(SE) of materials against electromagnetic pulse(EMP) that cannot be adequately evaluated by traditional test methods,a transfer function model of SE is *** homemade broadband coaxial fixture,the SE of a metal fabric material against square-pulse and electrostatic discharge(ESD) EMP is tested in the time *** peak SE calculated from the test results matches well with that obtained *** on the system identification theory,we propose the transfer function model of SE,which takes the square pulse and human body model ESD EMP data obtained in the tests as training data and takes the machine model as verification data,as well as a second-order expression of the transfer *** the transfer function model,the waveforms of the shield-penetrated square-pulse EMP and the ESD EMP are actually *** the perspective of system identification,this accurate prediction of the shielded waveform of EMP provides a reliable way for evaluating SE of materials against EMP.
