This book was released on 1978 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report describes a digital computer program which is designed to compute the terminal currents induced in a multiconductor transmission line by an incident electromagnetic field. Sinusoidal steady state behavior of the line is assumed. The transmission line is uniform and consists of n wires and a reference conductor immersed in a homogeneous, lossless, linear, isotropic medium. The n wires and the reference conductor are assumed to be lossless. The reference conductor may be a wire, an infinite ground plane or an overall, cylindrical shield. The incident electromagnetic field may be a uniform plane wave or a general nonuniform field. The primary restriction on the program validity is that the cross sectional dimensions of the line, e.g., wire separation, must be much less than a wavelength.

This book was released on 1977 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four digital computer programs, XTALK, XTALK2, FLATPAK, FLATPAK2, for determining the electromagnetic coupling within an (n+1) conductor, uniform transmission line are presented. Sinusoidal steady state behavior of the line as well as the TEM or 'quasi-TEM' mode of propagation are assumed. XTALK and XTALK2 consider lines consisting of n wires (cylindrical conductors) and a reference conductor. The surrounding medium is homogeneous and lossless. XTALK assumes that all (n+1) conductors are perfect conductors whereas XTALK2 considers the conductors to be lossy. There are three choices for the reference conductor: a wire, a ground plane, an overall cylindrical shield. FLATPAK and FLATPAK2 consider (n+1) wire ribbon (flatpack) cables in which all wires are identical and are coated with cylindrical, dielectric insulations of identical thicknesses. All wires lie in a horizontal plane and all adjacent wires are separated by identical distances. FLATPAK considers the wires to be perfect conductors and FLATPAK2 considers the wires to be lossy. The dielectric insulations are considered to be lossless. General termination networks are provided for at the ends of the line and the programs compute the voltages (with respect to the reference conductor) at the terminals of these termination networks for sinusoidal steady state excitation of the line.

Available in PDF, EPUB and Kindle. Book excerpt: This report discusses the excitation of a multiconductor transmission line by an incident electromagnetic field. Specific relations for the terminal (or load) response of a multiconductor line are derived in terms of field-induced voltage and current sources which are distributed along the transmission line. It is shown how these sources are derived for a general multiconductor line and how they may be derived from a knowledge of the incident (or free space) fields by using a field coupling parameter. The components of the exciting fields along the line are then given explicitly for the special case of an incident plane wave with arbitrary angle of incidence. (Author).

Paul and published by . This book was released on 1978 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: The prediction of crosstalk in ribbon cables is investigated. Experimental results are obtained for a 20 wire ribbon cable and compared to the predictions of the multiconductor transmission line (MTL) model. Based on the experimental configuration tested, it would appear that accurate predictions of crosstalk can be achieved in controlled characteristic cables such as these. The prediction accuracies are typically within + or - 1 dB for frequencies such that the line is electrically short (L 1/10 lambda) and + or - 6 dB for frequencies such that the line is electrically long (L 1/10 lambda). It was found that the parasitic wires in the cable can have a significant effect (as much as 40 dB for all frequencies) on the coupling between a generator circuit and a receptor circuit in the cable. Therefore to achieve accurate predictions in ribbon cables, one must consider the interactions between all wires in the cable. The wire insulation evidently can be ignored when the line is electrically short but cannot be ignored for higher frequencies. Conversely, the impedance of the reference wire cannot be ignored for low frequencies where the common impedance coupling dominates the electromagnetic field coupling. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: INTRODUCTION TO ELECTROMAGNETIC COMPATIBILITY The revised new edition of the classic textbook is an essential resource for anyone working with today’s advancements in both digital and analog devices, communications systems, as well as power/energy generation and distribution. Introduction to Electromagnetic Compatibility provides thorough coverage of the techniques and methodologies used to design and analyze electronic systems that function acceptably in their electromagnetic environment. Assuming no prior familiarity with electromagnetic compatibility, this user-friendly textbook first explains fundamental EMC concepts and technologies before moving on to more advanced topics in EMC system design. This third edition reflects the results of an extensive detailed review of the entire second edition, embracing and maintaining the content that has “stood the test of time”, such as from the theory of electromagnetic phenomena and associated mathematics, to the practical background information on U.S. and international regulatory requirements. In addition to converting Dr. Paul’s original SPICE exercises to contemporary utilization of LTSPICE, there is new chapter material on antenna modeling and simulation. This edition will continue to provide invaluable information on computer modeling for EMC, circuit board and system-level EMC design, EMC test practices, EMC measurement procedures and equipment, and more such as: Features fully-worked examples, topic reviews, self-assessment questions, end-of-chapter exercises, and numerous high-quality images and illustrations Contains useful appendices of phasor analysis methods, electromagnetic field equations and waves. The ideal textbook for university courses on EMC, Introduction to Electromagnetic Compatibility, Third Edition is also an invaluable reference for practicing electrical engineers dealing with interference issues or those wanting to learn more about electromagnetic compatibility to become better product designers.

This book was released on 1978 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: A transmission line model of the twisted wire pair is presented which may be used to compute electromagnetic coupling between the twisted wire pair and other circuits. The model is derived by representing the transmission line for the twisted wire pair as a cascade of uniform loops and 'abruptly' nonuniform twists. The overall transmission line matrix is found by cascading the chain parameter matrices, which represent the loops, with the permutation matrices, that represent the twists. Comparisons are presented between the twisted wire pair, the straight wire pair, and the single wire circuit configurations to determine the relative effectiveness in the reduction of electromagnetic coupling. Experimental results are compared to the model predictions which verify that the chain parameter model is accurate to within + or - 3 dB for frequencies such that the line is electrically short (i. e. 1/10 lambda). Finally a second model, the low frequency model, is presented and is shown to be as accurate as the chain parameter model in the prediction of coupling at low frequencies. This low frequency model is very appealing in that it is conceptually much easier to model and also less time consuming, computationally.

Book excerpt: This book provides a sound grasp of the fundamental concepts, applications, and practice of EMC. Developments in recent years have resulted in further increases in electrical component density, wider penetration of wireless technologies, and a significant increase in complexity of electrical and electronic equipment. New materials, which can be customized to meet EMC needs, have been introduced. Considerable progress has been made in developing numerical tools for complete system EMC simulation. EMC is now a central consideration in all industrial sectors. Maintaining the holistic approach of the previous edition of Principles and Techniques of Electromagnetic Compatibility, the Third Edition updates coverage of EMC to reflects recent important developments. What is new in the Third Edition? A comprehensive treatment of new materials (meta- and nano-) and their impact on EMC Numerical modelling of complex systems and complexity reduction methods Impact of wireless technologies and the Internet of Things (IoT) on EMC Testing in reverberation chambers, and in the time-domain A comprehensive treatment of the scope and development of stochastic models for EMC EMC issues encountered in automotive, railway, aerospace, and marine applications Impact of EMC and Intentional EMI (IEMI) on infrastructure, and risk assessment In addition to updating material, new references, examples, and appendices were added to offer further support to readers interested in exploring further. As in previous editions, the emphasis is on building a sound theoretical framework, and demonstrating how it can be turned to practical use in challenging applications. The expectation is that this approach will serve EMC engineers through the inevitable future technological shifts and developments.

This book was released on 1980 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contents of this report are concerned with the electromagnetic coupling (crosstalk) between braided-shield cables. The effect of pigtails (exposed sections of braided-shield cables in which the shield is stripped back exposing the interior wire) on crosstalk was investigated. It was found that even though the length of these exposed sections constitutes only a very small fraction of the total line length the dominant coupling to the shielded cable can occur via these pigtail sections. If the pigtail sections are eliminated, an additional reduction in crosstalk of as much as 30dB may be realized. The modeling and prediction of this crosstalk was also investigated. A low-frequency model provided accurate predictions for electrically short lines. The multiconductor transmission line (MTL) model was also formulated. The MTL model provided predictions within 1-3dB for electrically short lines and within 6-10dB when the line was electrically long.

This book was released on 1975 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The matrix formulation of the transmission line equations was applied in a semi-empirical manner to predict electromagnetic coupling with multiconductor transmission lines. Experimental procedures were used for measuring characteristic electrical parameters for transmission lines. The NLINE multiconductor transmission line computer program was used with experimental data for analysis of transmission-line samples made up of 2, 3, and 11 conductors. Parametric variations in angle of incidence and transmission line parameters were studied and compared with experimental results. The validity of simplifying approximations was checked with experimental data.
