Transient responses analysis of some ultra-wideband fliters in the presence of wideband electromagnetic pluses

It is well known that intentional or unintentional electromagnetic interference can impact on microwave circuits or systems to make them improper functionality, and in this paper, we analysis the transient responses of two ultrawideband (UWB) filters under a high-power EMP. Based on a modified FDTD method, numerical calculation is performed to show the EMP interference impacting on the S-parameters of UWB filters which are usually used in the wideband integration of communication circiuts and systems. The statistical analysis provides a new procedure for a confidence determination of the interference behavior parameters.
