Fundamentals of Power Semiconductor Devices

Today the semiconductor business exceeds $200 billion with about 10% of the revenue derived from power semiconductor devices and smart power integrated circuits. Power semiconductor devices are recognized as a key component for all power electronic systems. It is estimated that at least 50% of the electricity used in the world is controlled by power devices. With the widespread use of electronics in the consumer, industrial, medical, and transportation sectors, power devices have a major impact on the economy because they determine the cost and efficiency of systems. After the initial replacement of vacuum tubes by solid-state devices in the 1950s, semiconductor power devices have taken a dominant role with silicon serving as the base material. These developments have been referred to as the Second Electronic Revolution.

Fundamentals of Plasma Physics

This text is based on a course I have taught for many years to first year graduate and senior-level undergraduate students at Caltech. One outcome of this teaching has been the realization that although students typically decide to study plasma physics as a means towards some larger goal, they often conclude that this study has an attraction and charm of its own; in a sense the journey becomes as enjoyable as the destination. This conclusion is shared by me and I feel that a delightful aspect of plasma physics is the frequent transferability of ideas between extremely different applications so, for example, a concept developed in the context of astrophysics might suddenly become relevant to fusion research or vice versa. Applications of plasma physics are many and varied. Examples include controlled fusion research, ionospheric physics, magnetospheric physics, solar physics, astrophysics, plasma propulsion, semiconductor processing, and metals processing. Because plasma physics is rich in both concepts and regimes, it has also often served as an incubator for new ideas in applied mathematics. In recent years there has been an increased dialog regarding plasma physics among the various disciplines listed above and it is my hope that this text will help to promote this trend.

FUNDAMENTALS OF NUCLEAR SCIENCE AND ENGINEERING

Nuclear engineering and the technology developed by this discipline began and reached an amazing level of maturity within the past 60 years. Although nuclear and atomic radiation had been used during the first half of the twentieth century, mainly for medical purposes, nuclear technology as a distinct engineering discipline began after World War II with the first efforts at harnessing nuclear energy for electrical power production and propulsion of ships. During the second half of the twentieth century, many innovative uses of nuclear radiation were introduced in the physical and life sciences, in industry and agriculture, and in space exploration. The purpose of this book is two-fold as is apparent from the table of contents. The first half of the book is intended to serve as a review of the important results of "modern" physics and as an introduction to the basic nuclear science needed by a student embarking on the study of nuclear engineering and technology. Later in this book, we introduce the theory of nuclear reactors and its applications for electrical power production and propulsion. We also survey many other applications of nuclear technology encountered in space research, industry, and medicine.

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.
