The material presented in the report is intended to furnish a unified approach to understanding (1) the physical behavior of multiwire transmission lines as used in the realization of high-frequency electrical filters and couplers, and (2) the response of open-wire lines and of shielded cables to end excitation or to continuous excitation along the line by external electromagnetic fields. Scope of development is restricted entirely to monochromatic behavior of linear time-invariant systems, since, from that base, the response of the line to transient applied forces is readily synthesized by means of the Fourier theorem. The theory of lossless lines in homogeneous, isotropic dielectrics is applied in the derivation of basic line parameters of simple transmission line models. These parameters are related to the classical Maxwell capacitance coefficients. A number of practical configurations are discussed on which the designs of directional couplers, inductive and capacitive couplers, and wave filters, are based.

The essential textbook for electrical engineering students and professionals-now in a valuable new edition The increasing use of high-speed digital technology requires that all electrical engineers have a working knowledge of transmission lines. However, because of the introduction of computer engineering courses into already-crowded four-year undergraduate programs, the transmission line courses in many electrical engineering programs have been relegated to a senior technical elective, if offered at all. Now, Analysis of Multiconductor Transmission Lines, Second Edition has been significantly updated and reorganized to fill the need for a structured course on transmission lines in a senior undergraduate- or graduate-level electrical engineering program. In this new edition, each broad analysis topic, e.g., per-unit-length parameters, frequency-domain analysis, time-domain analysis, and incident field excitation, now has a chapter concerning two-conductor lines followed immediately by a chapter on MTLs for that topic. This enables instructors to emphasize two-conductor lines or MTLs or both. In addition to the reorganization of the material, this Second Edition now contains important advancements in analysis methods that have developed since the previous edition, such as methods for achieving signal integrity (SI) in high-speed digital interconnects, the finite-difference, time-domain (FDTD) solution methods, and the time-domain to frequency-domain transformation (TDFD) method. Furthermore, the content of Chapters 8 and 9 on digital signal propagation and signal integrity application has been considerably expanded upon to reflect all of the vital information current and future designers of high-speed digital systems need to know. Complete with an accompanying FTP site, appendices with descriptions of numerous FORTRAN computer codes that implement all the techniques in the text, and a brief but thorough tutorial on the SPICE/PSPICE circuit analysis program, Analysis of Multiconductor Transmission Lines, Second Edition is an indispensable textbook for students and a valuable resource for industry professionals.

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.

The new and original material in this book will appeal to a diversified audience. R&D microwave scientists will appreciate the use of a perturbation approach to modal analysis and generalized modal theory. Owing to its rigorous treatment of both theoretical issues and practical applications, it is sure to become an indispensable handbook for engineers concerned with the design and modelling of microwave circuits, telecommunications systems, or power systems.

Multiconductor transmission lines form the basic building blocks of microwave and millimeter-wave integrated circuits, and are omnipresent in digital systems. This book gives a detailed account of the way in which self-consistent computer-aided-design circuit models for such coupled lines, carrying either TEM or hybrid modes, can be obtained from a full-wave solution of Maxwell's equations. Latest advances for lossy lines are covered. The book also details the full-wave integral equation solution for basic transmission structures on MMICs, PCBs, and multiwire and microwire boards with the method of moments. For thin coupled microstrips and striplines the proposed space domain solution offers an alternative to the classical spectral domain approach. This book is the first to handle the full-wave analysis of discrete wire structures and of lossy polygonal conductors. The book is sure to appeal to a wide range of electrical and electronics engineers.
