This book discusses methods for measuring the water surface backscattering signature and estimating the near-surface wind vector over water using airborne radars, in addition to their standard application. Airborne FMCW demonstrator system, Doppler navigation system, airborne weather radar, airborne radar altimeter, and airborne precipitation radar are analyzed in order to be used for that purpose. The radars functionality is enhanced for their operation in a scatterometer mode. A circle flight and/or a rectilinear flight of an aircraft over the water surface is considered depending on the radar design features to perform measurements of the azimuth normalized radar cross section curve of the water surface and/or the near-surface wind speed and direction. Flight recommendations to perform measurements along with algorithms for measuring the water surface backscattering signature and for retrieval of the wind speed and direction over water are presented.

This book describes the recently-discovered artificially curved light beam known as the photonic hook. Self-bending of light, a long-time goal of optical scientists, was realized in 2007 with the Airy beam, followed by the first demonstration of the photonic hook by the authors of this book and their collaborators in 2015 and experimentally in 2019. The photonic hook has curvature less than the wavelength, along with other unique features described in this book that are not shared by Airy-like beams, and so deepens our understanding of light propagation. This book discusses the general principles of artificial near-field structured curved light and the full-wave simulations of the photonic hook along with their experimental confirmation. The book goes on to show how the photonic hook has implications for acoustic and surface plasmon waves and as well as applications in nanoparticle manipulation.

This textbook, based on the authors' class-tested material, is accessible to students at the advanced undergraduate and graduate level in physics and engineering. While its primary function is didactic, this book's comprehensive choice of topics and its clear and authoritative synthesis of ideas make it a useful reference for researchers, device engineers, and course instructors who wish to consolidate their knowledge of this field. The book takes the semi-classical approach where light is treated as a wave in accordance with the classical Maxwell equations, while matter is governed by quantum theory. It begins by introducing the postulates and mathematical framework of quantum theory, followed by the formalism of the density matrix which allows the transition from microscopic (quantum) quantities to macroscopic (classical) ones. Consequently, the equations describing the reaction of matter to the electromagnetic field in the form of polarization, magnetization, and current are derived. These equations (together with the Maxwell equations) form the complete system of equations sufficient to model a wide class of problems surrounding linear and nonlinear interactions of electromagnetic fields with matter. The nonlinear character of the governing equations determines parameters of the steady-state mode of the quantum generator and is also demonstrated in harmonic generation via propagation of laser radiation in various media. The touchstone description of magnetic phenomena will be of interest to scientists who deal with applications of magneto-resonance phenomena in biology and medicine. Other advanced topics covered include electric dipole transitions, magnetic dipole transitions, plasma transitions, and the devices that can be based on these and other electro-optical and nonlinear-optical systems. This textbook features numerous exercises, some of which are investigatory and some of which require computational solutions.

This is a specialized book for researchers and technicians of universities and companies who are interested in the fundamentals of RF power semiconductors, their applications and market penetration.Looking around, we see that products using vacuum tube technology are disappearing. For example, branch tube TVs have changed to liquid crystal TVs, and fluorescent light have turned into LED. The switch from vacuum tube technology to semiconductor technology has progressed remarkably. At the same time, high-precision functionalization, miniaturization and energy saving have advanced. On the other hand, there is a magnetron which is a vacuum tube device for generating microwaves. However, even this vacuum tube technology has come to be replaced by RF power semiconductor technology. In the last few years the price of semiconductors has dropped sharply and its application to microwave heating and energy fields will proceed. In some fields the transition from magnetron microwave oscillator to semiconductor microwave oscillator has already begun. From now on this development will progress remarkably. Although there are several technical books on electrical systems that explain RF power semiconductors, there are no books yet based on users' viewpoints on actual microwave heating and energy fields. In particular, none have been written about exact usage and practical cases, to answer questions such as "What are the advantages and disadvantages of RF power semiconductor oscillator?", "What kind of field can be used?" and the difficulty of the market and application. Based on these issues, this book explains the RF power semiconductors from the user's point of view by covering a very wide range of fields.

Finally, the history of optics is discussed.

This book provides a systematic description and analysis of laser heat-mode lithography, addressing the basic principles, lithography system, manipulation of feature size, grayscale lithography, resist thin films, and pattern transfer, while also presenting typical experimental results and applications. It introduces laser heat-mode lithography, where the resist thin films are essentially an opto-thermal response to the laser beam with changeable wavelength and are not sensitive to laser wavelength. Laser heat-mode lithography techniques greatly simplify production procedures because they require neither a particular light source nor a particular environment; further, there are no pre-baking and post-baking steps required for organic photoresists. The pattern feature size can be either larger or smaller than the laser spot by adjusting the writing strategy. The lithographic feature size can also be arbitrarily tuned from nanoscale to micrometer without changing the laser spot size. Lastly, the line edge roughness can be controlled at a very low value because the etching process is a process of breaking bonds among atoms. The book offers an invaluable reference guide for all advanced undergraduates, graduate students, researchers and engineers working in the fields of nanofabrication, lithography techniques and systems, phase change materials, etc.
