Alessia Candeo; Paolo Farinello; Cristian Manzoni; Giulio Cerullo 2013 Conference on Lasers & Electro-Optics Europe & International Quantum Electronics Conference CLEO EUROPE/IQEC, 2013

Ultrashort light pulses in the ultraviolet (UV) spectral range (λ<;400 nm) are required to study fundamental chemical and biological processes in biomolecules, which exhibit absorption in this region and ultrafast dynamics after photoexcitation. The generation of sub-10 fs UV pulses poses serious challenges in terms of: (i) broad bandwidth generation; (ii) pulse energy; (iii) spectral phase handling; (iv) pulse measurement. ...

  • Textile Antennas for Body Area Networks: Design Strategies and Evaluation Methods

    This chapter presents the design, development, and evaluation procedures for textile antennas. It overviews the types of textiles (conductive and non- conductive) and explains the characterization procedure using a commercial setup prior to the proposal of a systematic antenna fabrication procedure. In experiments, measurement of the reflection coefficient is performed using a vector network analyzer (VNA), whereas radiation characteristics, that is, patterns, gain, and efficiency are evaluated in an anechoic chamber. Antenna performance is assessed in the proximity of either a human user or a phantom and must lead to sufficient design information to guarantee this performance in the simulation-based design process, where the proximity of the human body also has to be taken into account. Finally, the chapter also describes the evaluation methods used for the fabricated antenna prototypes, that is, in terms of reflection coefficient, radiation characteristics, efficiency, and specific absorption rates (SAR).

  • Implanted Antennas and RF Transmission in Through-Body Communications

    This chapter focuses on radio frequency (RF) transmission characterization as well as the antenna designs for wireless capsule endoscopy and neural motor prosthetic devices. It reviews the key issues of RF or microwave signal propagation through body/head and implanted/external antennas of implanted medical devices. The key performances of the implanted/external antennas such as the impedance matching and antenna efficiency are affected by the lossy, inhomogeneous, and dispersive surrounding tissues. The chapter shows that the co-design of antenna with its surrounding tissues and biocompatible casing is needed in order to achieve optimum efficiency. It shows that to reduce the specific absorption rate (SAR) and enhance the transmission with the external receiver, an antenna with directional radiation is preferred. The system consists of three 32-channel implantable probe units for neural signal acquisition, a wearable head unit for neural signal acquisition, wireless telemetry, and wireless power transfer as well as an external base station.

  • Glossary

    A lucid and up-to-date introduction to understanding electrical power utilities in an era of change Electric utilities worldwide are undergoing profound transformations: nationally owned systems are becoming privatized, privately owned systems that were previously regulated are becoming deregulated, and national systems are becoming international. Professionals in the power sector must now work in a new world in which an understanding of the principles of markets and how to evaluate investment projects under competition are essential. This text was written as a manual for the Russian Federal Energy Commission to train regional electricity rate regulators in the principles of economics and finance involved in regulating electricity markets and deregulating electricity generation. Requiring no familiarity with economics and using a minimum of mathematics, this book provides professionals in the power sector with the tools to face the new realities of electric utility operation. Designed both as a reference for practicing professionals and as a textbook for university and continuing education programs, Electricity Economics: Regulation and Deregulation discusses: The lessons learned from international experiences Competitive versus noncompetitive markets Cost and supply, profit, and economic efficiency The cost of capital, including net present value, discounting, and risk and return Wholesale power markets, generation expansion, and customer choice Specific international examples including the Californian, Norwegian, Spanish, and Argentine power sectors Plus numerous exercises to help clarify and support absorption of the concepts

  • Vector Radiative Transfer

    Chapter 2 introduces the vector radiative transfer (VRT) theory of random media. It provides the scattering, absorption and extinction coefficients and the phase matrix of non-spherical scatterers in natural media. The first-order Mueller matrix solution of VRT for vegetation canopy model is derived. Polarization indexes, eigen-analysis and entropy are presented. Statistics of multi-look SAR images and covariance matrix are also investigated.

  • AMC-Backed Flexible Near-Endfire Wearable Antennas for On-Body Communications

    This chapter presents a multi-layered artificial magnetic conductor (AMC)-backed endfire planar Yagi antenna on a flexible latex substrate, such that the bidirectional-endfire radiation is altered to an off-axis beam tilt in the near-endfire direction. It discusses a novel technique of combining endfire radiation wearable planar antennas with AMCs for improving the antenna tolerance when positioned on the human body. A conventional planar Yagi antenna was combined with single- and double-layered AMC surfaces to change the direction of radiation from bidirectional-endfire to near-endfire off-axis beam-tilt radiation. The free-space and on-body analyses were performed using the CST MWS voxel model for common antenna properties, such as return loss, gain, frequency shifting, radiation efficiency, and peak specific absorption rate (SAR) level considering body-worn applications. The fabricated double- layered AMC-backed Yagi antenna prototype on latex substrate demonstrates acceptable return loss bandwidth and endfire gain to be used for wireless body area network (WBAN) applications in 2.4 GHz ISM band.
