Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to present the modern design principles and analysis of lens antennas. It gives graduates and RF/Microwave professionals the design insights in order to make full use of lens antennas. Why do we want to write a book in lens antennas? Because this topic has not been thoroughly publicized, its importance is underestimated. As antennas play a key role in communication systems, recent development in wireless communications would indeed benefit from the characteristics of lens antennas: low profile, and low cost etc. The major advantages of lens antennas are narrow beamwidth, high gain, low sidelobes and low noise temperature. Their structures can be more compact and weigh less than horn antennas and parabolic antennas. Lens antennas with their quasi-optical characteristics, also have low loss, particularly at near millimeter and submillimeter wavelengths where they have particular advantages. This book systematically conducts advanced and up-to-date treatment of lens antennas.

This book was released on 2012 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical antennas are metal nano structures that convert strongly localized energy into radiation and vice versa with a high throughput. Metals are not perfect conductors at optical frequencies and their optical properties are strongly affected by the existence of Surface Plasmon Polariton (SSP) resonances. These modes are highly confined and can be controlled at the nano scale by shape and size of metals. Although the principles of nano-optical antennas have been derived from conventional antennas, but the quantitative evaluation of antennas cannot be simply scaled down for nano antennas owing to the unusual behavior of metals at optical frequencies. Since the behavior of such nano antennas is dominated by surface Plasmon resonances, a numerical solution/simulation based on Maxwell's equation is necessary to study the effects of size of nano antenna, dielectric and illumination conditions on the field. The focus of this thesis is to analyze the scattered field of gold parabolic nano-disc. The research is based on the theory of conventional parabolic dish as an efficient structure for transmission and reception of energy. The field profile of the nano-disc provides insight into the behavior of the disc with respect to directivity, gain and field enhancement. This leads to the plasmonic applications in lasing cavities, photo voltaic cells, microscopy and spectroscopy. The simulation is carried out in COMSOL MULTIPHYSICS as it incorporates the Finite Element method (FEM) to solve the equations with the boundary condition.

Book excerpt: Combining a general introduction to Gaussian beams and quasioptical propagation with practical applications, Quasioptical Systems provides a state-of-the-art treatment of the design of low-loss, broadband systems at microwave to submillimeter wavelengths. The approach presented involves utilizing a beam with a Gaussian distribution of field strength perpendicular to its axis, which in turn propagates in a simple, predictable fashion.

Available in PDF, EPUB and Kindle. Book excerpt: Optical antennas have been widely used for variety of applications such as sensitive photodetection, efficient light emission, high-resolution imaging, heat-assisted magnetic recording, and surface-enhanced Raman spectroscopy (SERS) because they can capture and focus propagating electromagnetic energy into sub-diffraction-limited areas and vice versa. However, widespread application of optical antennas has been limited due to lack of appropriate methods for uniform and large area fabrication of antennas, as well as difficulty in achieving an efficient design with small mode volume (gap spacing
