This book presents innovative ideas and technical contributions in the area of metasurfaces and antenna technologies. On the one hand, it presents an effective method to analyze metasurfaces constituted by metallic texture with certain geometries. It shows how this method can be applied to the design of metasurface (MTS) antennas for deep space communications and other planar microwave devices. On the other hand, the book reports on a general methodology developed for analyzing flat devices realized by using modulated MTSs, which opens new design possibilities for a large number of microwave devices based on the manipulation of SWs. Finally, a novel approach of reconfigurability, which is based on a class of checkerboard MTS, is explored. All in all, this book covers important insights and significant results on the emerging topic of metasurfaces, from theoretical and computational aspects to experiments.

This book describes multi-site diversity modelling of induced rain attenuation statistics for satellite communication systems using copula functions. It gathers all relevant state-of-the-art knowledge, provides the missing pieces and rounds them up in a way that the reader is given a complete picture of important modelling factors and ways to address them. The books’ main features include: Data post-processing methodology for statistical analysis based on our Earth-satellite propagation experiments. Two novel multi-site diversity prediction models based on Gaussian copula considering distance between stations or considering distance, baseline, and elevation angle. Two novel multi-site diversity prediction models based on hyperbolic cosecant copula considering distance between stations or considering distance, baseline, and elevation angle. Exhaustive comparative tests and error performance of the prediction models showing that improved error performance is achieved compared to the ITU R model and to the state-of-the-art models. The results presented in the book are expected to contribute to the improvement of the system design and to the further research of modelling the next generation satellite links at higher frequencies.

Composites materials is basically the combining of unique properties of materials to have synergistic effects. A combination of materials is needed to adapt to certain properties for any application area. There is an everlasting desire to make composite materials stronger, lighter or more durable than traditional materials. Carbon materials are known to be attractive in composites because of their combination of chemical and physical properties. In the recent years, development of new composites has been influenced by precision green approaches that restrict hazardous substances and waste created during production. This book ranges from the fundamental principles underpinning the fabrication of different composite materials to their devices, for example, applications in energy harvesting, memory devices, electrochemical biosensing and other advanced composite-based biomedical applications. This book provides a compilation of innovative fabrication strategies and utilization methodologies which are frequently adopted in the advanced composite materials community with respect to developing appropriate composites to efficiently utilize macro and nanoscale features. The key topics are: Pioneer composite materials for printed electronics Current-limiting defects in superconductors High-tech ceramics materials Carbon nanomaterials for electrochemical biosensing Nanostructured ceramics and bioceramics for bone cancer Importance of biomaterials for bone regeneration Tuning hydroxyapatite particles Carbon nanotubes reinforced bioceramic composite Biomimetic prototype interface

Chipless RFID based on RF Encoding Particle: Realization, Coding and Reading System explores the field of chipless identification based on the RF Encoding Particle (REP). The book covers the possibility of collecting information remotely with RF waves (RFID) with totally passive tags without wire, batteries, and chips, and even printed on paper. Despite the many benefits of RFID, deployment is still hindered by several economic and technological factors. Among these barriers are the high cost of tags, lack of reliability and security in the information contained in the RFID chip, and how tags are 'recycled.' This book focuses on the development of chipless RFID tags, representing a new family of low cost tags. With this technology information is extracted from the electromagnetic response of the tag, which depends only on its geometry. Various solutions have been developed by the authors to increase the amount of information, reduce the surface of the tag, or improve the robustness of detection. Considerations such as realization using paper substrate, the development of a low cost detection system, and measurements in a real environment have been addressed for practical implementation. - Introduces the chipless RFID REP approach as compared to classical chipless RFID, RFID, and barcode technologies - Includes a demonstration of the practical and economic potential of chipless RFID technology, with detailed presentations and discussions of different test benches and comparisons - Presents in detail numerous examples of chipless tags that are able to tackle specific problems: sensitivity of detection, encoding density, robustness of detection, problem of tag orientation, tags and reader cost, and compliance with emission standards - Focuses on the development of chipless RFID tags, representing a new family of low cost tags
