FUNDAMENTALS OF LIGHT SOURCES AND LASERS

The field of photonics is enormously broad, covering everything from light sources to geometric and wave optics to fiber optics. Laser and light source technology is a subset of photonics whose importance is often underestimated. This book focuses on these technologies with a good degree of depth, without attempting to be overly broad and all-inclusive of various photonics concepts. For example, fiber optics is largely omitted in this book except when relevant, such as when fiber amplifiers are examined. Readers should find this book a refreshing mix of theory and practical examples, with enough mathematical detail to explain concepts and enable prediction of the behavior of devices (e.g., laser gain and loss) without the use of overwhelmingly complex calculus. Where possible, a graphical approach has been taken to explain concepts such as modelocking (in Chapter 7) which would otherwise require many pages of calculus to develop.

FUNDAMENTALS OF GAS DYNAMICS

This book is written for the average student who wants to learn the fundamentals of gas dynamics. It aims at the undergraduate level and thus requires a minimum of prerequisites. The writing style is informal and incorporates ideas in educational technology such as behavioral objectives, meaningful summaries, and check tests. Such features make this book well suited for self-study as well as for conventional course presentation. Sufficient material is included for a typical one-quarter or onesemester course, depending on the student’s background. Our approach in this book is to develop all basic relations on a rigorous basis with equations that are valid for the most general case of the unsteady, three-dimensional flow of an arbitrary fluid. These relations are then simplified to represent meaningful engineering problems for one- and two-dimensional steady flows. All basic internal and external flows are covered with practical applications which are interwoven throughout the text. Attention is focused on the assumptions made at every step of the analysis; emphasis is placed on the usefulness of the T –s diagram and the significance of any relevant loss terms.

Fundamentals of Engineering Electromagnetics

This volume, derived from the Handbook of Engineering Electromagnetics (2004), is intended as a desk reference for the fundamentals of engineering electromagnetics. Because electromagnetics provides the underpinnings for many technological fields such as wireless communications, fiber optics, microwave engineering, radar, electromagnetic compatibility, material science, and biomedicine, there is a great deal of interest and need for training in the concepts of engineering electromagnetics. Practicing engineers in these diverse fields must understand how electromagnetic principles can be applied to the formulation and solution of actual engineering problems.

Fundamentals of Computational Fluid Dynamics

The material in this book originated from attempts to understand and systemize numerical solution techniques for the partial differential equations governing the physics of fluid flow. As time went on and these attempts began to crystallize, underlying constraints on the nature of the material began to form. The principal such constraint was the demand for unification. Was there one mathematical structure which could be used to describe the behavior and results of most numerical methods in common use in the field of fluid dynamics? Perhaps the answer is arguable, but the authors believe the answer is affirmative and present this book as justification for that be- lief. The mathematical structure is the theory of linear algebra and the attendant eigenanalysis of linear systems.

Fundamentals In Nuclear Physics

Nuclear physics began one century ago during the “miraculous decade” between 1895 and 1905 when the foundations of practically all modern physics were established. The period started with two unexpected spinoffs of the Crooke’s vacuum tube: Roentgen’s X-rays (1895) and Thomson’s electron (1897), the first elementary particle to be discovered. Lorentz and Zeemann developed the the theory of the electron and the influence of magnetism on radiation. Quantum phenomenology began in December, 1900 with the appearance of Planck’s constant followed by Einstein’s 1905 proposal of what is now called the photon. In 1905, Einstein also published the theories of relativity and of Brownian motion, the ultimate triumph of Boltzman’s statistical theory, a year before his tragic death. For nuclear physics, the critical discovery was that of radioactivity by Becquerel in 1896.

Fundamental Numerical Methods and Data Analysis

The origins of this book can be found years ago when I was a doctoral candidate working on my thesis and finding that I needed numerical tools that I should have been taught years before. In the intervening decades, little has changed except for the worse. All fields of science have undergone an information explosion while the computer revolution has steadily and irrevocability been changing our lives. Although the crystal ball of the future is at best "seen through a glass darkly", most would declare that the advent of the digital electronic computer will change civilization to an extent not seen since the coming of the steam engine. Computers with the power that could be offered only by large institutions a decade ago now sit on the desks of individuals. Methods of analysis that were only dreamed of three decades ago are now used by students to do homework exercises. Entirely new methods of analysis have appeared that take advantage of computers to perform logical and arithmetic operations at great speed. Perhaps students of the future may regard the multiplication of two two-digit numbers without the aid of a calculator in the same vein that we regard the formal extraction of a square root. The whole approach to scientific analysis may change with the advent of machines that communicate orally. However, I hope the day never arrives when the investigator no longer understands the nature of the analysis done by the machine.

Приведен математический анализ диффузионной задачи применительно к эпитаксиальным структурам.

THE BIG BANG THEORY

A book like this depends on the work others have dedicated their careers to producing, others more specialized than I. Various cosmologists gave of their time to discuss modern cosmology, most notably Paul Steinhardt and David Spergel at Princeton and Jim Bardeen at the University of Washington. Information from discussions with Tom Siegfried, Charles Seife, and Phil Schewe—all great science writers—is also scattered throughout the book. Much of chapter 3 relies heavily on the ideas and research of Helge Kragh, professor of history of science at Aarhus University in Denmark. The standard story of how the big bang theory came to be accepted has been told so many times that it has turned into a modern myth. Professor Kragh, and historians like him, provide constant reminders that science doesn’t move in the perfect progression we’ve all been taught. He graciously offered advice and information, and his book Cosmology and Controversy was invaluable. Other fantastic books that were particularly helpful: The Big Bang by Joseph Silk, Blind Watchers of the Sky by Rocky Kolb, Afterglow of Creation by Marcus Chown, The Dancing Universe by Marcelo Gleiser, and The Runaway Universe by Donald Goldsmith.
