Electrodynamics Of Materials

This book is a detailed treatment of volume and surface force-densities and mechanical stresses in electrically and/or magnetically polarized bodies. The classical approach applies equally well to the electric and/or to the magnetic case. The issue of computation of force densities in materials is still a controversial one, but it is very important in many practical applications. These include the design of electric machines and various power apparatus, permanent magnet devices, and piezo-electric actuators and sensors. By combining electrodynamic theory, continuum mechanics and classical thermodynamics, important and reliable formulas for force densities are derived and settled. In particular, the well-known controversy between the Helmholtz and the Kelvin formulas for force densities in linear fluid dielectrics is analyzed in detail in the light of existing experimental results. * Thoroughly examines the role of mechanical stress tensor in electric and magnetic polarized materials; its connection with Maxwell's stress tensor is elucidated; the classical Cauchy's argument required to introduce the mechanic stress tensor (the Cauchy cut) is modified in such a way to be applicable to polarized materials * The constitutive relationships of polarized materials are derived from those holding for unpolarized materials * Closely examines the concept of electric and magnetic field energy and its connection with the thermodynamic internal energy of matter * Considers the role of magneto-hydro-statics (MHS) as a modern comprehensive theory including both magnetostatics and hydrostatics; describes several experimental MHS devices suited to test the theory * Examines magneticmaterials from both points of view: Coulombian and Amperian * Provides several different expressions for the resultant force and moment acting upon an electronically or magnetically polarized material body, and compares the two

This volume presents a state-of-the-art overview of the continuum theory of both electro- and magneto-sensitive elastomers and polymers, which includes mathematical and computational aspects of the modelling of these materials from the point of view of material properties and, in particular, the "smart-material" control of their mechanical properties.

This textbook can be used to teach electromagnetism to a wide range of undergraduate science majors in physics, electrical engineering or materials science. By making lesser demands on mathematical knowledge than typical texts, and by emphasizing electromagnetic properties of materials and their applications, this text is particularly appropriate for students of materials science. Many competing books focus on the study of propagation waves either in the microwave or optical domain, whereas Basic Electromagnetism and Materials covers the entire electromagnetic domain and the physical response of materials to these waves.

The authors of this book present a thorough discussion of the optical properties of solids, with a focus on electron states and their response to electrodynamic fields. A review of the fundamental aspects of the propagation of electromagnetic fields, and their interaction with condensed matter, is given. This is followed by a discussion of the optical properties of metals, semiconductors, and collective states of solids such as superconductors. Theoretical concepts, measurement techniques and experimental results are covered in three interrelated sections. Well-established, mature fields are discussed (for example, classical metals and semiconductors) together with modern topics at the focus of current interest. The substantial reference list included will also prove to be a valuable resource for those interested in the electronic properties of solids. The book is intended for use by advanced undergraduate and graduate students, and researchers active in the fields of condensed matter physics, materials science and optical engineering.

An engaging writing style and a strong focus on the physics make this graduate-level textbook a must-have for electromagnetism students.

The 1988 Nobel Prize winner establishes the subject's mathematical background, reviews the principles of electrostatics, then introduces Einstein's special theory of relativity and applies it to topics throughout the book.
