Electromagnetic Radiation is a graduate level book on classical electrodynamics with a strong emphasis on radiation. This book is meant to quickly and efficiently introduce students to the electromagnetic radiation science essential to a practicing physicist. While a major focus is on light and its interactions, topics in radio frequency radiation, x-rays, and beyond are also treated. Special emphasis is placed on applications, with many exercises and problems. The format of the book is designed to convey the basic concepts in a mathematically rigorous manner, but with detailed derivations routinely relegated to the accompanying side notes or end of chapter "Discussions". The book is composed of four parts: Part I is a review of basic E&M (electricity and magnetism), and presents a concise review of topics covered in the subject. Part II addresses the origins of radiation in terms of time variations of charge and current densities within the source, and presents Jefimenko's field equations as derived from retarded potentials. Part III introduces special relativity and its deep connection to Maxwell's equations, together with an introduction to relativistic field theory, as well as the relativistic treatment of radiation from an arbitrarily accelerating charge. A highlight of this part is a chapter on the still partially unresolved problem of radiation reaction on an accelerating charge. Part IV treats the practical problems of electromagnetic radiation interacting with matter, with chapters on energy transport, scattering, diffraction and finally an illuminating, application-oriented treatment of fields in confined environments.

"Menergy tells the story of a "post-disco" recording industry in San Francisco between the years 1978-1984. For most of America, disco died in 1979. Gay men, however, continued to dance, and in the gay enclave of the Castro neighborhood in San Francisco, enterprising gay DJs, record producers, and musicians started their own small dance music record labels to make up for the lack of new, danceable music. These independent labels' music did more than copy what the larger industry had been doing, however. Instead, the upstart companies built upon the musical experiments their roster of local musicians and producers had been exploring over the last several years, developing a distinctive style of its own. Known as "high energy," the music reveled in electronics, fast tempos, disco and DJ culture, and, above all, gay liberation as it had emerged over the previous decade in the Castro neighborhood by so called "Castro clones" (a gay subculture of exaggerated masculinity with a strong presence in the city's nightlife). The sound, like the new revolutionary ethos, derived its aesthetic from San Francisco's unique configuration of elements, but immediately this music had a reach far beyond the Bay, with Megatone Records, Moby Dick Records, and other labels achieving worldwide success with San Francisco artists such as Sylvester, Patrick Cowley, Paul Parker, Lisa, Loverde, and Jolo, creating the world's first gay-owned, gay-produced music for a dancing audience"--

The current volume offers a concise and analytical portrait of the contemporary world. The author encompasses concepts and theories from multiple disciplines notably sociology, anthropology, international relations, and economics to examine the major sociocultural transformations of the modern world, their underlying causes, and their consequences. The volume is organized in 10 chapters dealing with a variety of topics including global demographic trends, globalization, culture, foreign affairs, emerging markets, environmental degradation, global security, global health, large corporations, and economic inequality. Each chapter is divided into separate sections examining the accompanying themes. This book is a valuable reference for managers and business leaders, students, policy makers, and all those who are interested in acquiring a better understanding of the sociocultural trends that are shaping our world.

This book presents the vocabulary of a continually evolving and fundamental technical field which is finding ever broad applications in industry. It provides special attention to the language of national and international standards and recommendations, as well as appropriate field indications.
