Book Description
The propagation of a rectangular envelope carrier pulse through an inhomogeneous medium is proposed as a plasma diagnostic. The effect of electron collapse and other plasma parameters in producing the distortion of signal is studied. The distortion thus produced in the rectangular pulse is compared with that for the Gaussian carrier pulse. It is observed that the rectangular pulse is more distorted and hence it helps in the study of plasma parameters.

Book Description
Electromagnetic & Optical Pulse Propagation presents a detailed, systematic treatment of the time-domain electromagnetics with application to the propagation of transient electromagnetic fields (including ultrawideband signals and ultrashort pulses) in homogeneous, isotropic media which exhibit both temporal frequency dispersion and attenuation. The development is mathematically rigorous with strict adherence to the fundamental physical principle of causality. Approximation methods are based upon mathematically well-defined asymptotic techniques that are based upon the saddle point method. A detailed description is given of the asymptotic expansions used. Meaningful exercises are given throughout the text to help the reader‘s understanding of the material, making the book a useful graduate level text in electromagnetic wave theory for both physics, electrical engineering and materials science programs. Both students and researchers alike will obtain a better understanding of time domain electromagnetics as it applies to electromagnetic radiation and wave propagation theory with applications to ground and foliage penetrating radar, medical imaging, communications, and the health and safety issues associated with ultrawideband pulsed fields. 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-Debys 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.

Book Description
Waves in Layered Media focuses on the theory of the propagation of elastic and electromagnetic waves in layered media. This book presents a complete report of Soviet researches on wave propagation through layered media. Organized into six chapters, this book starts with an overview of the theory of wave reflection from layers and interfaces. This text then examines the some of the representations and methods, which are common to different branches of physics. Other chapters define the reflection reduction of optical waves as the lowering of the reflection coefficient at the air–glass boundaries by depositing thin layers of several materials on the glass. This book discusses as well the field of a concentrated source situated in a layered-inhomogeneous medium, which is one of the main problems in modern radiophysics, acoustics, and the physics of the Earth's crust. The final chapter deals with wave propagation in layered-inhomogeneous media. This book is a valuable resource for engineers, scientists, and physicists.

Book Description
The results of this analysis have direct, meaningful application to the analysis and design of low-observable surfaces (for stealth airframes) and ultra-wideband radar systems (for observing stealth airframes), the remote detection of buried structures (such as land-mines and IED's), ionospheric pulse propagation (for remote sensing from an orbiting satellite), as well as the problem of ultra-wideband electromagnetic pulse exposure of biological tissues. Of further interest is the application of this theory to undersea communications systems, terahertz optical communication and integrated optics systems, and the remote sensing of geophysical structures.
