Preface
Evaluation of the electromagnetic field due to transmission lines is an important problem in the field of electrical communications. Single transmission lines and small-scale electromagnetic waves typically utilize transmission line (TL) measurements, with trans magnetic (TEM) being the dominant transmission method. Classical TL theory neglects the antenna path, a high-frequency optical path.
Telegrapher Oliver Heaviside developed TL theory and its derivatives in the late 19th century, leading to significant advances in understanding wave propagation in communication lines. In 1965, Taylor, Satterwhite, and Harrison extended the classical TL parameters to include an external electromagnetic field. We have successfully used line transmission connectors and their equivalents to solve many problems related to EMP, lightning, and communications lines.
The rapid expansion of electronic devices and the emergence of various interference sources, including high-power microwave and ultra-wideband systems, have prompted many to question the validity of the TL theory. Over the past decade, adapting TL theory to account for frequency effects has emerged as an important topic of study in electrical engineering. This effort led to the development of the so-called “generalized” or “full-wave” TL theory, which incorporates the effects of high-wave radiation while retaining the relative simplicity of TL.
This book covers both traditional line distribution concepts and recent developments. The book is specifically tailored for graduate students, researchers, and engineers who are interested in propagation theory, electronic magnetic interactions, and propagation pathways, with a particular emphasis on multiple effects. The text divides into two main parts, each comprising seven chapters.
Part I provides combined information on classical linear types and various linear combinations.
Chapter 1 discusses the concept of TL and explains the origins of the field transmission equation. The chapter presents and discusses three mutually exclusive approaches proposed to explain the coupling of the electromagnetic field to the transmission line. Chapters 2 and 3 address specific issues of multi-line transmission lines and underground cables, respectively. We discuss various factors that contribute to the propagation of pulses in multiconductor systems and demonstrate calculation methods for long and transverse lines.
Part II presents several methods designed to generalize TL theory and incorporate critical effects.
In Chapter 4, the TL similarity equation was derived using a simple equation to evaluate the currents and potentials induced by an external electromagnetic field on a wire of a certain geometric shape on a good surface. Based on the stress theory, a regular method was developed to solve the stress due to coupling, in which the zero thrust term was determined using the TL equation. Chapter 5 presents an efficient mixing method for calculating more than electromagnetic field lines for long, load-carrying lines, including stopes. Chapter 6 demonstrates the generalizability of TL theory through its application to diverse problems. High-speed microelectronics and nanoelectronics frequently utilize a common derivative type. Chapter 7 mainly covers the electromagnetic field of underground cables. We have proposed and discussed two methods, one in the linear domain based on the Pocklington equation and the other in finite time using the Hallen integral equation.
We have made an effort to make each chapter as independent from the others as possible, even though the chapters follow a logical order and encourage beginning readers to read the book in order. Therefore, readers interested in a particular section covered in one chapter need not consult other parts of the book.
This book is the result of the authors’ work in the field of electromagnetic transmission lines. The authors are grateful to many people for their support, advice, and guidance. Michel Ianoz, Juergen Nitsch, and Fred M. We thank Tasche and all columnists for their contributions.
