New possibilities have recently emerged for producing optical beams with complex and intricate structures, and for the non-contact optical manipulation of matter. Structured Light and Its Applications fully describes the electromagnetic theory, optical properties, methods and applications associated with this new technology. Detailed discussions are given of unique beam characteristics, such as optical vortices and other wavefront structures, the associated phase properties and photonic aspects, along with applications ranging from cold atom manipulation to optically driven micromachines. Features include: Comprehensive and authoritative treatments of the latest research in this area of nanophotonics, written by the leading researchers Accounts of numerous microfluidics, nanofabrication, quantum informatics and optical manipulation applications Coverage that fully spans the subject area, from fundamental theory and simulations to experimental methods and results Graduate students and established researchers in academia, national laboratories and industry will find this book an invaluable guide to the latest technologies in this rapidly developing field.

Quadrature hybrids are passive circuit elements that are used in a wide range of RF and microwave applications, and this cutting-edge book is the first resource to provide engineers with a solid understanding of their characteristics and design. The book helps professionals use lumped element quadrature hybrids to achieve extremely wide bandwidth operation. This hands-on volume provides detailed construction techniques with worked examples, and describes the synthesis of circuits using practical circuit topologies. Moreover, the book discusses a wide-range of related topics, including active circuits, weak couplers, non-quadrature dividers, and tips on using graphical techniques. This comprehensive reference is thoroughly supported with over 225 illustrations and more than 200 equations.
