内容提要 波是代表物理系统的时空行为,波特征可以构成某些动力学的基本部分。本书共四章。章讨论了振动和波的基本原理;第二章讨论了波的数学概念;第三章讨论了波的各种性质;第四章对与一些实战技术相联系的波的传播进行了简短的描述,但并未详细介绍这些技术。 目录 PrefaceAuthor biography1 Introduction 1.1 Oscillatioand wave 1.2 Oscillatiodue to elastic force 1.2.1 Elastic force 1.2.2 Equatioof motion 1.2.3 Oscillatioas a solutioto equatioof motion 1.3 Frequency domaianalysis of oscillation 1.3.1 Fourier transform 1.4 Wave 1.4.1 Oscillatioto waveReferences2 Wave equations and solutions 2.1 Wave equation 2.1.1 Transverse waves 211.2 Longitudinal waves 2.1.3 Plane wave equation 2.1.4 Decaying wave 2.1.5 Some discussioophase velocity 2.2 Wave solutions 2.2.1 Plane wave solutions 2.2.2 Paraxial wave 2.2.3 Amplitude and phase of waves 2.2.4 Superpositioof waves and Fourier transformReferences3 Basic properties of waves 3.1 Reflectioand refraction 3.1.1 Angles of reflectioand refraction 3.1.2 Coefficient of reflectioand transmission 3.2 Dispersion 3.2.1 String oaelastic medium 3.2.2 Decaying wave 3.2.3 Light imatter 3.2.4 Transverse wave ibeam 3.2.5 Beads oa string 3.3 Interference 3.3.1 Optical interferometry 3.3.2 Acoustic interferometry 3.4 Diffraction 3.5 Doppler effectReferences4 Wave propagation 4.1 Group velocity 4.2 Resonator 4.3 Modulation 4.3.1 Amplitude modulation 4.3.2 Phase modulation 4.3.3 Frequency modulationReferences编辑手记 作者介绍 吉田三一郎,Sanichiro Yoshida received his undergraduate and graduate educations ithe field of Electrical Engineering and Applied Physics from Keio University, Japan. During this period, he had the opportunity to work as a student researcher at the University of Colorado Boulder. Under the supervisioof Dr. Author V. Phelps,he conducted research igaseous electronics. From this experience,he learned basics of scientific research. After receiving a PhD i1986 from Keio University, he has conducted experimental and theoretical research ovarious topics, including developments and applications of lasers, optical interferometry, optical and acoustical characterizatioof material strength, and deformatioand fracture of solids. His recent research interest is focused odevelopment of a wave theory of deformatioand fracture of solids. Currently, he is a Professor of Physics at SoutheasterLouisiana University where he enjoys research with students. Whenot doing science, he will be found othe Judo mats or tennis courts ocampus. 序言
