Photonic Crystals is the first book to address one of the newest and most exciting developments in physics--the discovery of photonic band-gap materials and their use in controlling the propagation of light. Recent discoveries show that many of the properties of an electron in a semiconductor crystal can apply to a particle of light in a photonic crystal. This has vast implications for physicists, materials scientists, and electrical engineers and suggests such possible developments as an entirely optical computer. Combining cutting-edge (...) research with the basic theoretical concepts behind photonic crystals, the authors present to undergraduates and researchers a concise, readable, and comprehensive text on these novel materials and their applications. The first chapters develop the theoretical tools of photonic crystals in a broad, intuitive fashion, starting from nothing more than Maxwell's equations and Fourier analysis, and include analogies to traditional solid-state physics and quantum theory. There follows an investigation of the unique phenomena that take place within photonic crystals, at defect sites, and at surfaces and interfaces. The authors offer a new treatment of the traditional multilayer film (a one-dimensional photonic crystal), which allows for the extension to higher dimensions and more complex geometries. After exploring the capabilities of photonic crystals to guide and localize light, the authors demonstrate how these notions can be put to work. (shrink)

Histories of Japanese science have been integral in affirming the Meiji Restoration of 1868 as the starting point of modern Japan. Vernacular genres, characterized as “premodern,” have therefore largely been overlooked by historians of science, regardless of when they were published. Paradoxically, this has resulted in the marginalization of the very works through which most people encountered science. This article addresses this oversight and its historiographical ramifications by focusing on kyūri books – popular works of science – published in the (...) years following the Restoration, when there was unprecedented public interest in science. It asks, what if we take these kyūri books on their own terms as science books, just as those of the time saw them? This article explores three genres of kyūri books, namely fictionalized formats, such as the epic tale ( monogatari); epistolary guides; and genres, such as the sutra, that drew on religious textual practices. It argues that these literary genres provided interpretive frameworks that shaped readers’ encounters with “modern” science. This exploration underscores the importance of engaging with vernacular genres to understand the emergence of science as a global category in the nineteenth century. (shrink)
