Abstract-A comprehensive review has been done on the types of electromagnetic transients that may affect low voltage electrical systems. The paper discusses various characteristics of lightning, switching, nuclear and intentional microwave impulses giving special attention to their impact on equipment and systems. The analysis shows that transients have a wide range of rise time, half peak width, action integral etc. with respect to both source and coupling mechanism. Hence, transient protection technology should be more specific with regard to the capabilities of the protection devices. Furthermore, we discuss the components and techniques available for the protection of low voltage systems from lightning generated electrical transients and the adequacy of International Standards in addressing the transient protection issues. The outcome of our analysis questions the suitability of 8/20 µs test current impulse in representing characteristics such as the time derivative and the energy content of lightning impulses. The 10/350 µs test current impulse better represents the integrated effects of the energy content of impulse component and long continuing current. A new waveform is required to be specified for testing the ability of protective devices to respond to the fast leading edges of subsequent strokes that may appear 100 s of millisecond after the preceding stroke. The test voltage waveform

Abstract-One novel dielectric conformal finite-difference timedomain (FDTD) method is used for computing specific absorption rate (SAR) distribution over the human body model in one metallic cabin with some windows on its wall. It is based on the concept of area average, which is different from other traditional conformal FDTD schemes. Our developed algorithm is verified by calculating both point and average SARs of dielectric sphere and human head models illuminated by an intentional electromagnetic pulse (IEMP), respectively, and CST Microwave Studio (MWS) also used for validating its accuracy. Numerical calculations are further performed to show the average SAR distribution over the human body model for different IEMP incidences, where the cabin door is opened or closed. The effects of E-field amplitude, direction and polarization of the incident IEMP on the SAR distributions are characterized in detail. This study will be useful for further electromagnetic protection for some persons working in high power exposure environment.

Abstract-An improved finite difference time domain (FDTD) method is employed for fast capturing transient responses of reconfigurable and multiple-input-multiple-output (MIMO) antennas under the impact of an intentional high-power electromagnetic pulse (EMP) but with different waveforms, respectively, where lumped element and sub-cellular thin-wire algorithms and coaxial feed model are integrated together for handling such three-dimensional antennas used for wireless communication. Parametric studies are carried out to show effects of high-power EMP waveforms, its polarization state and incident direction on the transient coupled voltages on the coaxial feed line and across the diodes, with sufficient information obtained for understanding the interaction between the EMP and the antennas.
