Theory of Reflection

Reflection and Transmission of Electromagnetic, Particle and Acoustic Waves

By: John Lekner

This book deals with the reflection of electromagnetic and particle waves by interfaces. The interfaces can be sharp or diffuse. The topics of the book contain absorption, inverse problems, anisotropy, pulses and finite beams, rough surfaces, matrix methods, numerical methods, reflection of particle waves and neutron reflection. Exact general results are presented, followed by long wave reflection, variational theory, reflection amplitude equations of the Riccati type, and reflection of short waves. The Second Edition of the Theory of Reflection is an updated and much enlarged revision of the 1987 monograph. There are new chapters on periodically stratified media, ellipsometry, chiral media, neutron reflection and reflection of acoustic waves. The chapter on anisotropy is much extended, with a complete treatment of the reflection and transmission properties of arbitrarily oriented uniaxial crystals. The book gives a systematic and unified treatment reflection and transmission of electromagnetic and particle waves at interfaces. It is intended for physicists, chemists, applied mathematicians and engineers, and is written in a simple direct style, with all necessary mathematics explained in the text.

Theory of Reflection of Electromagnetic and Particle Waves

By: John Lekner

This book is written for scientists and engineers whose work involves wave reflec tion or transmission. Most of the book is written in the language of electromagnetic theory, but, as the title suggests, many of the results can be applied to particle waves, specifically to those satisfying the Schr6dinger equation. The mathematical connection between electromagnetic s (or TE) waves and quantum particle waves is established in Chapter 1. The main results for s waves are translated into quantum mechanical language in the Appendix. There is also a close analogy between acoustic waves and electromagnetic p (or TM) waves, as shown in Section 1-4. Thus the book, though primarily intended for those working in optics, microwaves and radio, will be of use to physicists, chemists and electrical engineers studying reflection and transmission of particles at potential barriers. The tech niques developed here can also be used by those working in acoustics, ocean ography and seismology. Chapter 1 is recommended for all readers: it introduces reflection phenomena, defines the notation, and previews (in Section 1-6) the contents of the rest of the book. This preview will not be duplicated here. We note only that applied topics do appear: two examples are the important phenomenon of attenuated total reflection in Chapter 8, and the reflectivity of multilayer dielectric mirrors in Chapter 12. The subject matter is restricted to linear classical electrodynamics in non-magnetic media, and the corresponding particle analogues.

Theory of Electromagnetic Beams

Theory of Electromagnetic Beams

By: John Lekner

The theory of electromagnetic beams is presented in a simple and physical way, with all necessary mathematics explained in the text. The topics covered are in free-space classical electrodynamics, but contact is made with quantum theory in proofs that causal beams of various kinds can be viewed as superpositions of photons. This follows from explicit expressions for the energy, momentum and angular momentum per unit length for each type of beam. The properties of beams in the focal region, of special experimental and theoretical interest, are discussed in detail. There are eight chapters: on Fundamentals, Beam-like solutions of the Helmholtz equation, Electromagnetic beams, Polarization, Chirality, Comparison of electromagnetic beams, a chapter on Sound beams and particle beams (to show the similarities to and differences from the vector electromagnetic beams), and a final chapter on Measures of focal extent. Ten Appendices cover mathematical or associated physical topics.

Theory of Electromagnetic Pulses

By: John Lekner

This short monograph presents the theory of electromagnetic pulses in a simple and physical way. All pulses discussed are exact solutions of the Maxwell equations, and have finite energy, momentum and angular momentum. There are five chapters: on Fundamentals, Solutions of the Wave Equation, Electromagnetic Pulses, Angular Momentum, and Lorentz Transformations. Nine Appendices cover mathematical or associated aspects, such as chiral measures of electromagnetic fields. The subject matter is restricted to free-space classical electrodynamics, but contact is made with quantum theory in proofs that causal pulses are equivalent to superpositions of photons.

Philosophy and Engineering Education

New Perspectives, An Introduction

By: John Heywood,William Grimson,Jerry W. Gravander,Gregory Bassett,John Krupczak, Jr.

All educators bring to their work preconceived ideas of what the curriculum should be and how students learn. Seldom are they thought through. Since without an adequate philosophical base it is difficult to bring about desirable changes in policy and practice, it is necessary that educators have defensible philosophies of engineering education. This point is illustrated by recent debates on educational outcomes which can be analysed in terms of competing curriculum ideologies. While these ideologies inform the development of a philosophy of engineering education they do so in light of a philosophy of engineering for such a philosophy focuses on what engineering is, and in particular how it differs from science. This is addressed in this study through consideration of the differences in the modes of abstraction required for the pursuit of science on the one hand, and the pursuit of engineering design, on the other hand. It is shown that a philosophy of engineering is not a philosophy of science or a philosophy of engineering education, but it is from a philosophy of engineering that a philosophy of engineering education is drawn. Uncertainty is shown to be a key characteristic of engineering practice. A way of formulating a philosophy of engineering is to consider it through the classical prism that splits the subject into five divisions, namely epistemology, metaphysics, logic, ethics aesthetics. Additionally, “behaviour” also characterizes the practice of engineering.

Seeking News, Making China

Information, Technology, and the Emergence of Mass Society

By: John Alekna

Contemporary developments in communications technologies have overturned key aspects of the global political system and transformed the media landscape. Yet interlocking technological, informational, and political revolutions have occurred many times in the past. In China, radio first arrived in the winter of 1922-23, bursting into a world where communication was slow, disjointed, or non-existent. Less than ten percent of the population ever read newspapers. Just fifty years later, at the beginning of the Cultural Revolution, news broadcasts reached hundreds of millions of people instantaneously, every day. How did Chinese citizens experience the rapid changes in information practices and political organization that occurred in this period? What was it like to live through a news revolution? John Alekna traces the history of news in twentieth century China to demonstrate how large structural changes in technology and politics were heard and felt. Scrutinizing the flow of news can reveal much about society and politics—illustrating who has power and why, and uncovering the connections between different regions, peoples, and social classes. Taking an innovative, holistic view of information practices, Alekna weaves together both rural and urban history to tell the story of rise of mass society through the lens of communication techniques and technology, showing how the news revolution fundamentally reordered the political geography of China.

Condensed Matter Theories

By: Susana Hernandez,John W. Clark, Jr.

Drawn from the 24th International Workshop on Condensed Matter Theories (Buenes Aires, Sep. 2000) these 45 papers, while centered on the concepts and techniques of condensed-matter physics, also address broad issues of common concern for theorists who apply advanced many-particle methods in other areas of physics. Five primary topics are covered by the contributions: quantum liquids, boson condensates, strongly-correlated electron systems, superconductivity and superfluidity, and phase transitions. Some of examples of specific questions addressed include shot noise of mesoscopic quantum systems, heat transport in superlattices, transitions from non-colinear to conlinear structures in a magnetic multilayer model, order-disorder transitions in a vortex lattice, perturbation theory in the one-phase region of an electron-ion system, and nonlinear dynamics in metal clusters. c.

Designing Engineering and Technology Curricula

Designing Engineering and Technology Curricula

Embedding Educational Philosophy

By: John Heywood

The intention of this book is to demonstrate that curriculum design is a profoundly philosophical exercise that stems from perceptions of the mission of higher education. Since the curriculum is the formal mechanism through which intended aims are achieved, philosophy has a profound role to play in the determination of aims. It is argued that the curriculum is far more than a list of subjects and syllabi, or that it is the addition, and subtraction, of items from a syllabus, or whether this subject should be added and that subject taken away. This book explores how curricular aims and objectives are developed by re-examining the curriculum of higher education and how it is structured in the light of its increasing costs, rapidly changing technology, and the utilitarian philosophy that currently governs the direction of higher education. It is concluded that higher education should be a preparation for and continuing support for life and work, a consequence of which is that it has to equip graduates with skill in independent learning (and its planning), and reflective practice. A transdisciplinary curriculum with technology at its core is deduced that serves the four realities of the person, the job, technology, and society.
