Ordered and Disordered Metamaterials

The exotic electromagnetic behaviours of metamaterials have created a large knowledge base showing their importance in designing varieties of optical and electronic components/devices of great technological use, namely antennas, filters, absorbers, sensors, energy harvesters etc., operating in certain frequency ranges.

This book provides a detailed introduction to the basic metamaterial modelling approaches and an overview of innovative phenomena enabled by metamaterials. The book covers discussions on the fundamental formalisms used in the study of metamaterials comprising the ordered and disordered configurations of meta-atoms. The book also illustrates the application of these in different directions, such as designing antennas and radars, multi-controllable sensors, perfect absorbers, tuneable devices, and biological sensors. This way the book incorporates studies of active metamaterials with tuneable and switchable properties, novel functionalities such as the control of spontaneous emission and enhancement along with the practical applications of the disordered metamaterial concept. The topics addressed cover the major strands: theory, modelling and design, applications in practical devices, fabrication, characterization, and measurement. It is worth mentioning that the strategic objectives of developing new artificial functional materials require close cooperation of research in each of these subareas. This book provides a useful tool for both the current and future participants (academics and/or professionals) in the area of photonics by presenting methodologies for sustainable materials for energy harvesting and sensing, health diagnostics, meeting the needs of a range of readers from students to early career researchers to established scientists in their fields.
