Impedance of a nanoantenna F. Parabolic Antenna One of the useful properties of this antenna is the conversion of a diverging spherical wavefront into a parallel wavefront that produces a narrow beam of the antenna. This introduction to antenna theory and design is suitable for senior undergraduate and graduate courses on the subject.

Even if their functionality is similar optical and RF antennas show drastic differences in physics material properties and excitation features. In this paper we review some of the concepts of optical antenna theory design and applications and we highlight how the optical nanocircuit paradigm may be applied to achieve optical impedance matching loading.

In this paper a unified theory is developed to design optical nano-antenna arrays which are able to manipulate light similarly to how antenna arrays manipulate RF radiation. Elsherbeni Colorado School of Mines USA.

As their name indicates they make use of a lens to modify the field distribution at the aperture of the antenna which is typically fed by a single source. Fundamentals From near-field optics to optical antennas by D. For the development of analytical models of more complex antenna structures.

Antenna Theory Performance and Design Analysis Characteristics Communication Wireless applications. By Andrea Alù The University of Texas at Austin Nader Engheta University of Pennsylvania Edited by Mario Agio Andrea Alù University of Texas Austin. 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.

Here inspired by optical antenna theory we address this challenge by introducing chiral antenna parameters. Similar to radiofrequency RF antennas optical antennas which operate in the visible and near-infrared NIR frequency regions can pick up energies efficiently from propagating electromagnetic EM waves at the frequencies of interest and transfer EM energies from one point to another. Some new developments covered in the book include a rapid design method for inhomogeneous metamaterials microwave and RF applications of.

From near-field optics to optical antennas D. The authors describe in detail design procedures for a wide range of applications including broadband multi-band multi-beam contour-beam beam-scanning and conformal reflectarray antennas. These antennas have four distinct advantages.
