Propagation of Electrial Fast Transient (EFT) in Radiation mode and its impacts on Equipment under Test

This paper demonstrates the propagation of the Electrical fast transient in Radiation mode (air mode) while the testing is done in conducted mode (wire mode) and its effects on the Equipment under Test. This paper gives solutions to protect the equipment under test immune from this noise in Radiated mode (air medium) since the test is done in conducted mode (wire Medium) and the product desingner unaware of the radiated noise coupling while taking protection against Equipment under Test.
