Optical Antennas

This consistent and systematic review of recent advances in optical antenna theory and practice brings together leading experts in the fields of electrical engineering, nano-optics and nano-photonics, physical chemistry and nanofabrication. Fundamental concepts and functionalities relevant to optical antennas are explained, together with key principles for optical antenna modelling, design and characterisation. Recognising the tremendous potential of this technology, practical applications are also outlined. Presenting a clear translation of the concepts of radio antenna design, near-field optics and field-enhanced spectroscopy into optical antennas, this interdisciplinary book is an indispensable resource for researchers and graduate students in engineering, optics and photonics, physics and chemistry.

Mario Agio is a Senior Researcher at the National Institute of Optics (INO-CNR) and the European Laboratory for Nonlinear Spectroscopy (LENS), Florence, Italy. His research interests focus on single-molecule spectroscopy and optical nanoscopy, quantum- and nonlinear-optics in photonic nanostructures, plasmonics and metamaterials. He has been awarded the Latsis Prize of ETH-Zurich for his significant contributions to the field of theoretical nano-optics.
Andrea Alù is an Assistant Professor at the University of Texas, Austin, whose research interests span metamaterials and plasmonics, miniaturised antennas and nanoantennas, nanocircuits and nanostructure modelling. He received the 2012 SPIE Early Career Achievement Award, and the 2011 URSI Issac Koga Gold Medal for his contributions to the theory and application of electromagnetic metamaterials.
