It has been known from the previous chapter that light, and in general,
electromagnetic waves have particle behavior. Some latter time than the quantum theory of light, it was discovered
that particles show also wavelike behavior.
The wave-particle duality of matter is the fundamental concept of
Newton’s classical physics should be replaced by the new mechanics
which is able to describe the wave nature of particles
Vibrations are a part of our environment and daily life. Many of them are useful and are
needed for many purposes, one of the best example being the hearing system. Nevertheless,
vibrations are often undesirable and have to be suppressed or reduced, as they may be harmful
to structures by generating damages (possibly leading to dramatic and spectacular accidents
such as the case of the Aloha 243 fl ight or the bridge of Tacoma Narrows) or compromise the
comfort of users through noise generation of mechanical wave transmission to the body....
Microwaves are generally considered to be a specific part of the wide radio
frequency spectrum. The band from 300 MHz to 30 GHz is typically considered
to be “microwaves,” for example by the Institute of Electrical end
Electronics Engineers (IEEE), although many of us prefer to set the lower
limit somewhat higher—perhaps at 1 or even 3 GHz. Above 30 GHz, the
term “millimeter waves” is used. High school physics suggests that we are
talking about wavelengths ranging from about 30 cm down to 10 mm...
This book is dedicated to various aspects of electromagnetic wave theory and its
applications in science and technology. The covered topics include the fundamental
physics of electromagnetic waves, theory of electromagnetic wave propagation and
scattering, methods of computational analysis, material characterization,
electromagnetic properties of plasma, analysis and applications of periodic structures
and waveguide components, and finally, the biological effects and medical
applications of electromagnetic fields....
This text/reference is the only one of its kind to offer the basics on surface wave mechanics and coastal processes along with the fundamentals of coastal engineering analysis and design. It also provides the necessary background from which the reader can pursue a more advanced study of the various theoretical and applied aspects of coastal hydromechanics and coastal engineering design.
The concept of acoustic wave is a pervasive one, which emerges in any type of medium, from solids to plasmas, at length and time scales ranging from sub-micrometric layers in microdevices to seismic waves in the Sun's interior. This book presents several aspects of the active research ongoing in this field. Theoretical efforts are leading to a deeper understanding of phenomena, also in complicated environments like the solar surface boundary.
This book presents a fluid mechanics perspective to the dynamics of fronts and vortices and their interaction with waves in geophysical flows. It provides a basic physical background for modeling coherent structures in a geophysical context, and it gives essential information on advanced topics such as spontaneous wave emission and wavemomentum transfer in geophysical flows. Based on a set of lectures by leading specialists, this text is targeted at graduate students, researchers and engineers in geophysics and environmental fluid mechanics.
Surface Acoustic Wave (SAW) devices are widely used in multitude of device concepts mainly
in Micro Electro Mechanical Systems (MEMS) and communication electronics. As such,
SAW based micro-sensors, actuators and communication electronic devices are well known
applications of SAW technology. Due to their solid state design and fabrication compatible
with other modern technologies such as Microwave Integrated Circuits (MIC), MEMS, (Charge
Coupled Devices) CCD and integrated optic devices, SAW based sensors are considered to be
Lately, there has been a growing interest in electromagnetic wave propagation in
complex systems such as modern materials and structures. This book is intended to
give the explanatory 20 chapters which consist of original works of the leading scientists
in the field of wave propagation which produced theoretical and experimental
methods in this field of research and obtained important results.
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.
Acoustics is a discipline that deals with many types of fields wave phenomena.
Originally the field of Acoustics was consecrated to the sound, that is, the study of
small pressure waves in air detected by the human ear. The scope of this field of
physics has been extended to higher and lower frequencies and to higher intensity
levels. Moreover, structural vibrations are also included in acoustics as a wave
phenomena produced by elastic waves. This book is focused on acoustic waves in
fluid media and elastic perturbations in heterogeneous media....
I have great pleasure in introducing this e-book “Frontiers in Guided Wave Optics and
Optoelectronics” under the new series Advances in Lasers and Electro Optics being
published by IN-TECH Publishers. Guided wave optics and optoelectronics are at the heart
of optical communications, optical signal processing, miniaturization of optical components,
biomedical optics, defense applications, and so on.
This book deal with the modern developing of microwave and millimeter wave technologies.
The first chapter is aimed at describing the evolution of technological processes for the design
of passive functions in millimetre-wave frequency range. From the results HR SOI seems to
be a good candidate in the coming year to address both low cost and low power mass market
CMOS digital and RF/ MMW applications.
Today, the development and use of microwave (3-30 GHz) and millimeter wave (30-300 GHz)
band is being actively promoted. Microwave has been used extensively since the Second World
War when the sources were based on vacuum devices. Microwaves are presently playing a
vital role in RADAR, land and satellite based communication and also have wide civilian and
defence applications. Two typical areas of application of millimeter-wave are information
communication and remote sensing.

On the auditory. Goals of chapters-lectures presented. Three basic parts of the book. Structure of the single chapter-lecture. On comments. On bibliography. On questions. Waves in the world around. Materials in the world around.
The book is proposed for the auditory moderately educated in the field of mechanics and mathematics. It does not assume that the presence of elementary knowledge only will be sufficient for its understanding.
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.
