Page 2 of 46 www.PDHcenter.com PDHonline Course E402 www.PDHonline.org Introduction An electromagnetic pulse (EMP) is a burst of electromagnetic radiation that results from the detonation of a nuclear weapon and/or a suddenly fluctuating magnetic field. The resulting rapidly changing electric fields and magnetic fields may couple with electric systems to produce damaging current and voltage surges. In military terminology, a nuclear bomb detonated hundreds of kilometers above the Earth's surface is known as a high-altitude electromagnetic pulse (HEMP) device. Nuclear electromagnetic pulse has three distinct time components that result from different physical phenomena. Effects of a HEMP device depend on a very large number of factors, including the altitude of the detonation, energy yield, gamma ray output, interactions with the Earth's magnetic field, and electromagnetic shielding of targets.

Box 1450 • Goleta, California 93116 Metatech FOREWORD This report has been written to provide an overview of Intentional Electromagnetic Interference (IEMI) threats to the electric power infrastructure. It is based on the past 10 years of research by the authors and their colleagues who have been active in the field. Some of the information provided here is adapted from the IEEE Special Issue on HPEM and IEMI published in the IEEE EMC Transactions in August 2004. Additional information is presented from recent published papers and conference proceedings. This report begins in Section 1 by explaining the background and terminology involved with IEMI. Section 2 summarizes the types of EM weapons that have been built and the IEMI environments that they produce. Section 3 provides insight concerning the basic EM coupling process for IEMI and why certain threat waveforms and frequencies are important to commercial systems. Section 4 provides a selection of commercial equipment susceptibility data covering important categories of equipment that may be affected by IEMI. Section 5 discusses more specific aspects of the IEMI threat for the power system, and Section 6 indicates the IEC standardization efforts that can be useful to understanding the threat of IEMI and the means to protect equipment from the threat.

  • High Isolation Flyback Transformer Technical Article
    HIGH ISOLATION VOLTAGE FLYBACK TRANSFORMER By: Edgar C. Taculog Field Application Engineer, Asia TT Electronics New TT Electronics AEC-Q200 qualified and certified transformers are optimized for use with a gate- drive optocoupler to improve and simplify the design of isolated power supplies. Overview Transformers can often provide an inexpensive solution for a variety of applications. The purpose of the transformer is to isolate the secondary side of the circuit from the primary power source, transfer power efficiently from the electrical source to the target load and protect users from hazards like electric shock, fire and heat. The flyback transformer, which is an isolated version of a buck-boost transformer, does not in truth contain a transformer but a coupled inductor arrangement. When the transistor is turned on, current builds up in the primary and energy is stored in the core, this energy is then released to the output circuit through the secondary when the switch is turned off. The basic concept of this scenario can result in significant heat generation if not properly addressed.

  • High Altitude Electromagnetic Pulse (HEMP) and High Power Microwave (HPM) Devices: Threat Assessments
    Order Code RL32544 High Altitude Electromagnetic Pulse (HEMP) and High Power Microwave (HPM) Devices: Threat Assessments Updated July 21, 2008 Clay Wilson Specialist in Technology and National Security Foreign Affairs, Defense, and Trade Division High Altitude Electromagnetic Pulse (HEMP) and High Power Microwave (HPM) Devices: Threat Assessments Summary Electromagnetic Pulse (EMP) is an instantaneous, intense energy field that can overload or disrupt at a distance numerous electrical systems and high technology microcircuits, which are especially sensitive to power surges. A large scale EMP effect can be produced by a single nuclear explosion detonated high in the atmosphere. This method is referred to as High-Altitude EMP (HEMP). A similar, smaller-scale EMP effect can be created using non-nuclear devices with powerful batteries or reactive chemicals. This method is called High Power Microwave (HPM). Several nations, including reported sponsors of terrorism, may currently have a capability to use EMP as a weapon for cyber warfare or cyber terrorism to disrupt communications and other parts of the U.S. critical infrastructure. Also, some equipment and weapons used by the U.S. military may be vulnerable to the effects of EMP. The threat of an EMP attack against the United States is hard to assess, but some observers indicate that it is growing along with worldwide access to newer technologies and the proliferation of nuclear weapons. In the past, the threat of mutually assured destruction provided a lasting deterrent against the exchange of multiple high-yield nuclear warheads. However, now even a single, low-yield nuclear explosion high above the United States, or over a battlefield, can produce a large-scale EMP effect that could result in a widespread loss of electronics, but no direct fatalities, and may not necessarily evoke a large nuclear retaliatory strike by the U.S.

  • Simulation of Electromagnetic Pulse Propagation Through Dielectric Slabs with Finite Conductivity Using Characteristic-Based Method
    PIERS ONLINE, VOL. 2, NO. 6, 2006 609 Simulation of Electromagnetic Pulse Propagation through Dielectric Slabs with Finite Conductivity Using Characteristic-based Method Mingtsu Ho Department of Electronic Engineering, WuFeng Institute of Technology Chia Yi 621, Taiwan Abstract| This paper presents one-dimensional simulation results of electromagnetic pulse propagation through various dielectric slabs. The material used in the numerical model is assumed to be homogeneous and isotropic such that its dielectric constant, relative permeability, and conductivity are not functions of the time and independent of the electric and magnetic ¯eld intensities. The computational results are generated by the characteristic-based method and compared in a side-by-side fashion. The e®ects of medium conductivity on the reflected and transmitted pulses are recorded and shown as time elapses. Also revealed is how the medium conductivity a®ects the electromagnetic pulses for dielectric slabs that are impedance matched to free space, i. e., "r = ¹r. The frequency-domain results are illustrated that are obtained through the application of FFT to the time-domain data. DOI: 10.2529/PIERS060825013017 1. INTRODUCTION The method of moment (MoM) and the ¯nite-di®erence time-domain (FDTD) technique have been the two most popular computational electrodynamics modeling techniques ever since they were proposed in 60 s [1, 2]. The latter can be formulated for either time- or frequency-domain analysis while the former is only in frequency-domain. Numerical simulation results always provide researchers a much more perceptive view of a variety of electromagnetic phenomena and therefore give researchers a better understanding of the problem of interest.
