A wave is one of the basic physics phenomena observed by mankind since ancient time. The wave is also one of the most-studied physics phenomena that can be well described by mathematics. The study may be the best illustration of what is “science”, which approximates the laws of nature by using human defined symbols, operators, and languages.
We studied theoretically and experimentally the transformation, attenuation, and setup due to shoaling and breaking of internal waves in a two-layer fluid system on a uniform slope. An image processing technique was used to illustrate 2D instantaneous displacements of density interface. These results were compared with the calculated values by using the method of characteristics, the simple shoaling model with energy dissipation, and the momentum balance equation based on a radiation stress concept.
Wave propagation in solids has been widely studied and principal advances in this field have been achieved not only for the improvements of calculus methods, but also for the high progresses attained in the description of new types of materials. This book presents innovative and original research studies describing some enhancement in both directions.
This chapter presents the following content: Reflection of uniform plane waves at normal incidence, standing wave ratio, wave reflection from multiple interfaces, plane wave propagation in general directions, plane wave reflection at oblique incidence angles, wave propagation in dispersive media.
(BQ) Ebook Microwave Engineering emphasizes the fundamental concepts of Maxwell's equations, wave propagation, network analysis and design principles as applied to modern microwave engineering. Applications of microwave engineering are also changing, with increasing emphasis on commercial use of microwave technology for personal communications systems, wireless local area networks, millimeter wave collision avoidance vehicle radars, radio frequency (RF) identification tagging, direct broadcast satellite television, and many other systems related to the information infrastructure.
In the recent decades, there has been a growing interest in micro- and nanotechnology. The advances in nanotechnology give rise to new applications and new types of materials with unique electromagnetic and mechanical properties. This book is devoted to the modern methods in electrodynamics and acoustics, which have been developed to describe wave propagation in these modern materials and nanodevices.
This book is based on the contributions of several authors in electromagnetic waves
propagations. Several issues are considered. The contents of most of the chapters are
highlighting non classic presentation of wave propagation and interaction with
matters. This book bridges the gap between physics and engineering in these issues.
Each chapter keeps the author notation that the reader should be aware of as he reads
from chapter to the other. The author’s notations are kept in order to eliminate any
possible unintentional errors that might lead to confusion.
The book collects original and innovative research studies of the experienced and actively working scientists in the field of wave propagation which produced new methods in this area of research and obtained new and important results. Every chapter of this book is the result of the authors achieved in the particular field of research. The themes of the studies vary from investigation on modern applications such as metamaterials, photonic crystals and nanofocusing of light to the traditional engineering applications of electrodynamics such as antennas, waveguides and radar investigations....
