Synopsis Reception and Transmission of Transient Electromagnetic Fields by : Hans J. Schmitt
The receiving and transmitting properties of small linear antennas, conical antennas, and loops for transient electromagnetic fields were investigated experimentally. Short electrical dipoles loaded by a capacitance represented by a cathode follower can be used successfully for the measurement of transient fields with rise times of less than 1 nanosecond, if the first antenna resonance is suppressed by a series resistor at the base of the antenna. The currents induced on nonresonant structures by transient electromagnetic fields are investigated and their application to a direct measurement of the time sequence of the electromagnetic field is discussed. Signals with a simple and known time dependence such as a unidirectional pulse can be radiated into space if the reflection of current waves at discontinuities of the antenna structure is avoided. In a manner similar to that useful for the absorption of continuous waves in media with a stratified conductivity, it is shown that reflections at discontinuities can be avoided by dipoles with tapered resistive loading.

Synopsis The Propagation of Electromagnetic Waves in Multiconductor Transmission Lines by : P. I. Kuznetsov
The Propagation of Electromagnetic Waves in Multiconductor Transmission Lines presents the study of the problems relating to the propagation of electromagnetic waves along multi-conductor transmission line. This book examines the theoretical investigations into the propagation of electromagnetic waves in transmission line systems involving two or more conductors. Organized into 12 chapters, this book begins with an overview of the rigorous method based on Maxwell's equations for solving the basic problem in the theory of the steady-state propagation of electromagnetic waves in a multi-conductor system. This text then examines the significant practical problem of determining the electromagnetic fields of symmetrical and non-symmetrical two-wire lines in free space. Other chapters consider the methods of calculating the parameters of non-uniform lines. This book discusses as well the problem of transient electromagnetic processes in a multi-conductor system. The final chapter deals with the asymptotic representation of cylindrical functions of two-imaginary variables. Electrical engineers will find this book useful.

Synopsis Electromagnetic Field Interaction with Transmission Lines by : Farhad Rachidi
The evaluation of electromagnetic field coupling to transmission lines is an important problem in electromagnetic compatibility. Traditionally, use is made of the TL approximation which applies to uniform transmission lines with electrically small cross-sectional dimensions, where the dominant mode of propagation is TEM. Antenna-mode currents and higher-order modes appearing at higher frequencies are neglected in TL theory. The use of the TL approximation has permitted to solve a large range of problems (e.g. lightning and EMP interaction with power lines). However, the continual increase in operating frequency of products and higher frequency sources of disturbances (such as UWB systems) makes that the TL basic assumptions are no longer acceptable for a certain number of applications. In the last decade or so, the generalization of classical TL theory to take into account high frequency effects has emerged as an important topic of study in electromagnetic compatibility. This effort resulted in the elaboration of the so-called 'generlized' or 'full-wave' TL theory, which incorporates high frequency radiation effects, while keeping the relative simplicity of TL equations. This book is organized in two main parts. Part I presents consolidated knowledge of classical transmission line theory and different field-to-transmission line coupling models. Part II presents different approaches developed to generalize TL Theory.
