This book addresses the modelling of mechanical waves by asking the right questions about them and trying to find suitable answers. The questions follow the analytical sequence from elementary understandings to complicated cases, following a step-by-step path towards increased knowledge. The focus is on waves in elastic solids, although some examples also concern non-conservative cases for the sake of completeness. Special attention is paid to the understanding of the influence of microstructure, nonlinearity and internal variables in continua. With the help of many mathematical models for describing waves, physical phenomena concerning wave dispersion, nonlinear effects, emergence of solitary waves, scales and hierarchies of waves as well as the governing physical parameters are analysed. Also, the energy balance in waves and non-conservative models with energy influx are discussed. Finally, all answers are interwoven into the canvas of complexity.

Travelling wave processes and wave motion are of great importance in many areas of mechanics, and nonlinearity also plays a decisive role there. The basic mathematical models in this area involve nonlinear partial differential equations, and predictability of behaviour of wave phenomena is of great importance. Beside fluid dynamics and gas dynamics, which have long been the traditional nonlinear scienes, solid mechanics is now taking an ever increasing account of nonlinear effects. Apart from plasticity and fracture mechanics, nonlinear elastic waves have been shown to be of great importance in many areas, such as the study of impact, nondestructive testing and seismology. These lectures offer a thorough account of the fundamental theory of nonlinear deformation waves, and in the process offer an up to date account of the current state of research in the theory and practice of nonlinear waves in solids.

This book provides a comprehensive treatment of electromagnetic waves. The author's approach is thoroughly modern, and unlike many others, this text offers a unified view of electromagnetic waves and their applications in telecommunications, radar, and photonics. The extensive coverage of Electromagnetic Waves begins with Maxwell's equations and takes students on the journey from the wave and Helmholtz equations through polarization, plane waves, and wave beams and packets, to antennas, transmission lines, and waveguides. Completing the treatment are chapters devoted to diffraction and an introduction to the theory of coherence. The author strikes an effective balance of the teach-through-concepts and teach-by-example approaches. The book is filled with exercises, current applications, and exercises that solidify students' understanding and bring relevance to the material. It forms an outstanding text for senior undergraduates and graduate-level students in electrical engineering and physics.

The study of vibrations and waves is central to physics and engineering disciplines.This text contains a detailed treatment of vibrations and waves at an introductory level suitable for second and third year students. It builds on first year physics and emphasizes understanding of vibratory motion and waves based on first principles. Since waves appear in almost all branches of physics and engineering, readers will be exposed to many different types of waves; this study aims to draw together their similarities, by examining them in a common language. The book is divided into three parts: Part I contains a preliminary chapter that serves as a review of relevant ideas of mechanics and complex numbers. Part II is devoted to a detailed discussion of vibrations of mechanical systems. This part covers simple harmonic oscillator, coupled oscillators, normal coordinates, beaded string, continuous string, and Fourier series. It concludes with a presentation of stationary solutions of driven finite systems. Part III is concerned with waves, focusing on the discussion of common aspects of all types of waves, and the applications to sound, electromagnetic, and matter waves are illustrated. Finally, relevant examples are provided at the end of the chapters to illustrate the main ideas, and better the reader's understanding.

Sitting on the beach on a sunny summer day, we enjoy the steady advance and retreat of the waves. In the water, enthusiastic waders jump and shriek with pleasure when a wave hits them. But where do these waves come from? How are they formed and why do they break on the shore? In Waves, Fredric Raichlen traces the evolution of waves, from their generation in the deep ocean to their effects on the coast. He explains, in a way that is readily understandable to nonscientists, both the science of waves themselves and the technology that can be used to protect us against their more extreme forms, including hurricanes and tsunamis. After offering a basic definition of waves and explaining the mechanics of wind-wave generation, Raichlen describes how waves travel, how they shoal (rise), how they break, and how they transform in other ways. He goes on to describe, among other things, the complicated sun-Earth-moon combinations that create astronomical tides (the high and low tides that occur daily and predictably); the effects of waves on the beach, including rip currents and beach erosion, and on harbors and shipping; and the building of breakwaters to protect harbors and bays. He discusses hurricanes, storm surges, and hurricane-generated waves. He offers a brief history of tsunamis, including Sumatra's in 2004 and Japan's in 2011, and explains the mechanisms that generate them (including earthquakes, landslides, and volcanoes). Waves can be little ripples that lap peacefully at the shore or monstrous tsunamis that destroy everything in their paths. Describing the science underlying this astonishing variety, Waves offers a different kind of beach reading.

Rayleigh-Wave Theory and Application

There is no respect for mere age in Science or Technology. Yet the cen tenary of the discovery, by the third Lord Rayleigh, that elastic waves can be guided by a surface, is memorable for the contradictions which it encompasses: Rayleigh's assessment of his classic 1885 paper as a rather minor mathematical development with a potential value only in seismology on the one hand; on the other the rediscovery of the subject in a totally that of electronic signal processing - which has led to its different fiel- explosive growth over the last twenty years. The new surface acoustic wave (SAW) devices have proved to be per electronic components. Today almost all television receivers con vasive tain one or more SAW filters, sophisticated radars depend on SAW signal processing, and SAW devices have been incorporated in ultra-high perfor mance opto-electronic systems. With the objective of surveying these developments and attempting to predict those that can be foreseen, as well as marking the centenary of Lord Rayleigh's discovery, The Rank Prize Funds' Committee for Opto Electronics organised a symposium in London, in July 1985. It was held in the Royal Institution, London, where Rayleigh himself once worked and often lectured. The present volume is the tangible outcome of the symposium, In which international experts survey.ed their various fields, and presented the most exciting recent developments.

This textbook offers a complete and rigorous presentation of the fundamentals and applications of wave optics. The material of the book covers topics on wave nature of light—reflection, refraction, polarisation, diffraction, dispersion and scattering of electromagnetic waves. Interference phenomenon is discussed both by division of wavefront and by division of amplitude. Diffraction is classified as Fresnel diffraction and Fraunhofer diffraction. The discussion on Fraunhofer diffraction has been used to explain the theory and resolving power of optical instruments. The role of phenomena of dispersion and scattering of light has been lucidly explained in the field of communication of information, its quality and content. The last three chapters are devoted to the study of the recently developed modern topics—lasers, holography, and fibre optics—all of which have opened up immense opportunities for new applications in almost all branches of science and engineering. Though the book is intended for the undergraduate students of physics—both honours and general courses—it will also be useful to candidates aspiring to sit the competitive examinations. KEY FEATURES : Presents interactive text interspersed with in-text questions to enable students to shift focus on active learning. Uses access devices such as expected learning outcomes and practice exercises for directed teaching–learning. Includes numerous worked-out examples to illustrate the concepts and provides review questions to test the students’ understanding of the subject. Gives chapter-end summary for quick revision of the important results.

The Physics of Oscillations and Waves

With Applications in Electricity and Mechanics

Author: Ingram Bloch

Publisher: Springer Science & Business Media

ISBN: 1489900500

Category: Science

Page: 318

View: 9505

Except for digressions in Chapters 8 and 17, this book is a highly unified treatment of simple oscillations and waves. The phenomena treated are "simple" in that they are de scribable by linear equations, almost all occur in one dimension, and the dependent variables are scalars instead of vectors or something else (such as electromagnetic waves) with geometric complications. The book omits such complicated cases in order to deal thoroughly with properties shared by all linear os cillations and waves. The first seven chapters are a sequential treatment of electrical and mechanical oscillating systems, starting with the simplest and proceeding to systems of coupled oscillators subjected to ar bitrary driving forces. Then, after a brief discussion of nonlinear oscillations in Chapter 8, the concept of normal modes of motion is introduced and used to show the relationship between os cillations and waves. After Chapter 12, properties of waves are explored by whatever mathematical techniques are applicable. The book ends with a short discussion of three-dimensional vii viii Preface problems (in Chapter 16), and a study of a few aspects of non linear waves (in Chapter 17).

Vor fünfzig Jahren verfällt William Finnegan dem Surfen. Damals verschafft es ihm Respekt, dann jagt es ihn raus in die Welt – Samoa, Indonesien, Australien, Südafrika –, als Familienvater mit Job beim New Yorker dient es der Flucht vor dem Alltag ... Barbarentage erzählt die Geschichte dieser lebenslangen Leidenschaft, sie handelt vom Fernweh, von wahren Abenteuern und den Versuchen, trotz allem ein Träumer zu bleiben. Ein Buch wie das Meer, atemberaubend schön. »Wie Into the Wild erzählt dieses Buch auf mitfühlende, kluge Weise, was passiert, wenn Ideen von Freiheit einen jungen Menschen erfassen und in die entlegensten Winkel der Welt hinausschleudern.« The New York Times Magazine »Fesselnde Abenteuergeschichte, intellektuelle Autobiografie, rastlose Meditation über Liebe, Freundschaft und Familie ... Barbarentage ist ein Buch von ergreifender Schönheit und wird Surfer und Nichtsurfer gleichermaßen begeistern.« Washington Post »Das zu lesen, was dieser Kerl über Wellen und Wasser schreibt, ist wie Hemingway über Stierkämpfe zu lesen, William Burroughs über Drogen und Updike über Ehebruch.« Sports Illustrated
