In this book, a wide range of different topics related to analytical as well as numerical solutions of problems related to scattering, propagation, radiation, and emission in different medium are discussed. Design of several devices and their measurements aspects are introduced. Topics related to microwave region as well as Terahertz and quasi-optical region are considered. Bi-isotropic metamaterial in optical region is investigated.

This volume presents the results of research on Arabian continental vertebrates discovered in the United Arab Emirates, the Sultanate of Oman, and the Republic of Yemen. The contributors provide information on Arabian palaeontology, stratigraphical, geological, isotropic and palaeomagnetic topics.
Thermodynamics is one of the most exciting branches of physical chemistry which has greatly contributed to the modern science. Being concentrated on a wide range of applications of thermodynamics, this book gathers a series of contributions by the finest scientists in the world, gathered in an orderly manner. It can be used in post-graduate courses for students and as a reference book, as it is written in a language pleasing to the reader. It can also serve as a reference material for researchers to whom the thermodynamics is one of the area of interest....
My introduction to membranes was as a graduate student in 1963. At that time
membrane permeation was a sub-study of materials science. What is now called
membrane technology did not exist, nor did any large industrial applications
of membranes. Since then, sales of membranes and membrane equipment have
increased more than 100-fold and several tens of millions of square meters of
membrane are produced each year—a membrane industry has been created.

We shall consider the scattering of a plane, linearly polarized monochromatic wave by a perfectly conducting prolate spheroid immersed in a homogeneous isotropic medium. Solution of the EM scattering by the oblate spheroid can be obtained by the transformations 5 --+ it and c --+ -ic. It is assumed that the surrounding medium is nonconducting and nonmagnetic. The geometry of the configuration is shown in Fig. 4.1, and the surface of the spheroid is given by
So, given PT and G it is possible to calculate the power density at any point in the far ®eld that lies in the direction of maximum radiation. A knowledge of the radiation pattern is necessary to determine the power density at other points. The power gain is unity for an isotropic antenna, i.e. one which radiates uniformly in all directions, and an alternative de®nition of power gain is therefore the ratio of power density, from the speci®ed antenna, at a given distance in the direction of maximum radiation, to the power density at the same point, from an isotropic...
EM Scattering by a Coated Dielectric Spheroid
5.1 GEOMETRY OF THE PROBLEM In this chapter we consider the scattering of a linearly polarized plane monochromatic wave by a homogeneous lossy/lossless dielectric spheroid with a confocal lossy/lossless dielectric coating immersed in a homogeneous isotropic medium. It is assumed that the surrounding medium is nonconducting and nonmagnetic
This book focuses on the current research in the area of rheology. Rheological characterizations are performed on materials in order to understand the basic nature of a system, quality control of raw materials and final products. The rheological characterizations are important to study the effect of different parameters such as formulation, shelf life and temperature on the quality of final products.

NMR in solids, like solution-state, relies
on the behavior of nuclear spin energy
levels in a magnetic field. However, the
interactions that affect NMR spectra act
In liquids, molecules reorient and
diffuse quickly, leading to narrow
In solids, the fixed orientation of
individual crystallites leads to a range
of resonance frequencies for
Monte-Carlo modeling allows calculating the detector efficiency in gamma spectrometry of environmental samples with taking into consideration both the photon selfabsorption in sample itself and absorption in all other materials between the sample and the detector’s active part. In this paper, the peak efficiencies of the Hp Ge detector (GMX) for gammas at various energies (emitted isotropically from the standard disk source and volumetric source - environmental sample, in which the different radionuclides are present) ...
The process, as described in step (c) is repeated for a shorter time to expose
the bottom silicon surface for further dry etching, as shown in Fig. 9(g). In order to expose sidewalls for
the wet etch release, the structure is deepened using a similar multi-step dry etch process as described in
step (d), except that low energy, high pressure isotropic dry etching is used instead of high energy, high
pressure to preserve the less robust silicon dioxide that had taken the place of Cr as the etch mask. This
deepening of the structure determines the gap between the...
Construction of bounds on the elastic moduli of isotropic multicomponent materials which involve three-point correlation parameters. We use numerical methods to study several representative material models. Construction of three-point correlation bounds on the effective elastic shear modulus of composite materials and applications of the bounds are given to some composites.
The first reported CMOS-MEMS processes produce
microstructural sidewalls by stacking the drain/source con-
tact cut and metal via cuts in the CMOS and removing the
metallization layers above the cuts . The substrate is
exposed in the cut regions. A wet or dry isotropic silicon
etch undercuts and releases the microstructures. Gaps
between microstructures are limited to several microns
because of artifacts in the etch pits from etching metal
above the CMOS contacts.
