Book Description
Does that transmission line, which connects your antenna and transmitter, seem like a mystery to you? Or perhaps your have other questions: Just how much of the transmitter's rated output power actually gets to the antenna? How much power is consumed by the line itself? Just what is the input impedance of the antenna? Or, what is the input impedance at the transmitter end of a transmission line when the antenna is connected to its other end? Why does my tuner seem to work better on some bands than others? What is the effect of high transmission line SWR? Should I be concerned about high SWRs? What can I do about them? It is the unusual operator who has not at one time or another asked one or more of these questions. Well, now you can easily answer these questions and many others! Using simple language the author of this book, a former electronic design engineer and amateur over more than 60 years, shows how to find the answers, quickly, easily and accurately. Those more technically inclined can work with the equations provided by the book; those who just want answers without all the math can use a personal computer and specially developed, easy-to-use programs from a CD and get accurate answers directly with the click of a button! But there is more: the book contains many solved examples and each solution is followed by a thorough discussion. Now you can get answers while you learn about transmission lines.

Book Description
High frequencies of densely packed modern electronic equipment turn even the smallest piece of wire into a transmission line with signal retardation, dispersion, attenuation, and distortion. In electromagnetic environments with high-power microwave or ultra-wideband sources, transmission lines pick up noise currents generated by external electromagnetic fields. These are superimposed on essential signals, the lines acting not only as receiving antennas but radiating parts of the signal energy into the environment. This book is outstanding in its originality. While many textbooks rephrase that which has been written before, this book features: an accessible introduction to the fundamentals of electromagnetics; an explanation of the newest developments in transmission line theory, featuring the transmission line super theory developed by the authors; a unique exposition of the increasingly popular PEEC (partial element equivalent circuit) method, including recent research results. Both the Transmission Line Theory and the PEEC method are well suited to combine linear structures with circuit networks. For engineers, researchers, and graduate students, this text broadens insight into the basics of electrical engineering. It provides a deeper understanding of Maxwellian-circuit-like representations of multi-conductor transmission lines, justifies future research in this field.

Book Description
The re-engineering of power transmission systems is crucial to meeting the objectives of such regulators as the European Union. In addition to its market, organisational and regulatory aspects, this re-engineering will also involve technical issues dealing with the progressive integration of innovative transmission technologies in the daily operation of transmission system operators. In this context, Advanced Technologies for Future Transmission Grids provides an overview of the most promising technologies, likely to be of help to planners of transmission grids in responding to the challenges of the future: security of supply; integration of renewable generation; and creation of integrated energy markets (using the European case as an example). These issues have increased importance because of administrative complication and the fragmentation of public opinion expressed on the build up of new infrastructure. For each technology discussed, the focus is on the technical-economic perspective rather than on purely technological points of view. A transmission-system-operator-targeted Technology Roadmap is presented for the integration of promising innovative power transmission technologies within power systems of the mid-long term. Although the primary focus of this text is in the sphere of the European energy market, the lessons learned can be generalized to the energy markets of other regions.

Book Description
Despite the dramatic growth in the availability of powerful computer resources, the EM community lacks a comprehensive text on the computational techniques used to solve EM problems. The first edition of Numerical Techniques in Electromagnetics filled that gap and became the reference of choice for thousands of engineers, researchers, and students. This third edition of the bestselling text reflects the continuing increase in awareness and use of numerical techniques and incorporates advances and refinements made in recent years. Most notable among these are the improvements made to the standard algorithm for the finite-difference time-domain (FDTD) method and treatment of absorbing boundary conditions in FDTD, finite element, and transmission-line-matrix methods. The author also has added a chapter on the method of lines. Numerical Techniques in Electromagnetics with MATLAB®, Third Edition continues to teach readers how to pose, numerically analyze, and solve EM problems, to give them the ability to expand their problem-solving skills using a variety of methods, and to prepare them for research in electromagnetism. Now the Third Edition goes even further toward providing a comprehensive resource that addresses all of the most useful computation methods for EM problems and includes MATLAB code instead of FORTRAN.

Book Description
This book presents the topic in electromagnetics known as Transmission-Line Modeling or Matrix method-TLM. While it is written for engineering students at graduate and advanced undergraduate levels, it is also highly suitable for specialists in computational electromagnetics working in industry, who wish to become familiar with the topic. The main method of implementation of TLM is via the time-domain differential equations, however, this can also be via the frequency-domain differential equations. The emphasis in this book is on the time-domain TLM. Physical concepts are emphasized here before embarking onto mathematical development in order to provide simple, straightforward suggestions for the development of models that can then be readily programmed for further computations. Sections with strong mathematical flavors have been included where there are clear methodological advantages forming the basis for developing practical modeling tools. The book can be read at different depths depending on the background of the reader, and can be consulted as and when the need arises.
