This book describes cutting edge research and development on electromagnetic vortex waves including their related wave properties and a variety of potential transformative applications. It is divided into three parts. The first part presents the generation sorting manipulation and interesting wave behavior of vortex waves in the infrared and optical regimes with custom designed nanostructures. The second cluster deals with the generation multiplexing propagation of vortex waves at microwave and millimeter wave frequencies. The last group of chapters exhibit several representative practical applications of vortex waves from a system perspective ranging from microwave frequencies to optical wavelengths. Each chapter is contributed by an internationally recognized author or group of authors covering the latest research results
