Book excerpt: "Electromagnetic Fields in Stratified Media" deals with an important branch of electromagnetic theory, which has many useful applications in subsurface communication, radar, and geophysical prospecting and diagnostics. The book introduces to the electromagnetic theory and wave propagation in complex media, while presenting detailed models for various media: 3, 4, N-layered media, boundary conditions, and anisotropic media. In particular, the complete solutions for a trapped surface wave and lateral wave in a three- or four-layered region, the complete solutions for low frequency wave propagation over a spherical surface coated with a dielectric layer, and the transient field of a horizontal dipole in the boundary layer of two different media are presented. The book is designed for the scientists and engineers engaged in antennas and propagation, EM theory and applications. Dr. Kai Li is Professor at Zhejiang University.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: In two volumes, this book presents a detailed, systematic treatment of electromagnetics with application to the propagation of transient electromagnetic fields (including ultrawideband signals and ultrashort pulses) in dispersive attenuative media. The development in this expanded, updated, and reorganized new edition is mathematically rigorous, progressing from classical theory to the asymptotic description of pulsed wave fields in Debye and Lorentz model dielectrics, Drude model conductors, and composite model semiconductors. It will be of use to researchers as a resource on electromagnetic radiation and wave propagation theory with applications to ground and foliage penetrating radar, medical imaging, communications, and safety issues associated with ultrawideband pulsed fields. With meaningful exercises, and an authoritative selection of topics, it can also be used as a textbook to prepare graduate students for research. Volume 2 presents a detailed asymptotic description of plane wave pulse propagation in dielectric, conducting, and semiconducting materials as described by the classical Lorentz model of dielectric resonance, the Rocard-Powles-Debye model of orientational polarization, and the Drude model of metals. The rigorous description of the signal velocity of a pulse in a dispersive material is presented in connection with the question of superluminal pulse propagation. The second edition contains new material on the effects of spatial dispersion on precursor formation, and pulse transmission into a dispersive half space and into multilayered media. Volume 1 covers spectral representations in temporally dispersive media.
Download or read book Lateral Electromagnetic Waves written by Ronold W.P. King and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 771 pages. Available in PDF, EPUB and Kindle. Book excerpt: The propagation of waves along and across the boundary between two media with different characteristic velocities is much more complicated when the source is on or near the boundary than when it is far away and the incident waves are plane. Examples of waves generated by localized sources near a boundary are the electromagnetic waves from the currents in a dipole on the surface of the earth and the seismic waves from a slip event in a fault in the earth's crust like the San Andreas fault in California. Both involve a type of surface wave that is called a lateral wave in electro magnetics and a head wave in seismology. Since the two are analogous and the latter is more easily visualized, it is conveniently used here to introduce and describe this important type of surface wave using the data of Y. Ben Zion and P. Malin ("San Andreas Fault Zone Head Waves Near Parkfield, CA," Science 251, 1592-1594, 29 March 1991).

Download or read book Electromagnetics of Time Varying Complex Media written by Dikshitulu K. Kalluri and published by CRC Press. This book was released on 1998-07-29 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in the fields of materials science and electromagnetics indicate that materials can be synthesized with any desired electromagnetic properties. Electromagnetics of Complex Media provides the appropriate understanding of optimum properties for a given application, addressing the needs of researchers who study electromagnetics as a base for those disciplines using complex materials. Examples include electrooptics, plasma science and engineering, microwave engineering, and solid state devices.The book emphasizes these aspects: Dispersive medium Tunneling of power through a plasma slab by evanescent waves Characteristic waves in an anisotropic medium Transient medium and frequency shifting Green's function for unlike anisotropic media Perturbation technique for unlike anisotropic media Adiabatic analysis for modified source wave All of the above topics use one-dimensional models. Brief discussions also include chiral media, surface waves, and periodic media. The text focuses on bringing out the major effects due to each kind of complexity in the medium properties. A plasma column in the presence of a static magnetic field is at once dispersive, anisotropic, and inhomogeneous - thus the author uses plasma as the basic medium to illustrate some aspects of the transformation of an electromagnetic wave by a complex medium. Early chapters use a mathematical model that usually has one kind of complexity. The medium is often assumed to be unbounded in space or has a simple plane boundary. The field variables and the parameters are often assumed to vary in one spatial coordinate. This eliminates the use of heavy mathematics and permits the focus to be on the effect. Electromagnetics of Complex Media aims to stimulate experimental and additional theoretical and numerical work on the effects that can be obtained by the temporal and spatial modification of the magnetoplasma parameters. The book also provides the new researcher with a quick primer into the theory of using magnetoplasmas for the coherent generation of tunable radiation.
