Testing of materials shielding effectiveness against electromagnetic pulse

摘要

In order to meet the requirements of time-domain test of materials shielding effectiveness (SE), a time-domain SE of materials test system against electrostatic discharge (ESD) electromagnetic pulse (EMP) was presented. Combined with the homemade broadband coaxial test fixture, the SE of silver-plated fabric material was tested by employing ESD EMP and the paper calculated the material peak SE. The experiment result was matched with the theoretical calculated result. The time-domain test system can be used for the reliable evaluation of materials shielding effectiveness against EMP.
