Available in PDF, EPUB and Kindle. Book excerpt: L'identification par radiofrequence est une technologie qui connait un essor colossal et exige la reduction du cout de revient d'une etiquette electronique pour repondre au developpement de son marche. Ce document a ete consacre a la conception des antennes de tags RFID en bande UHF. Le cahier des charges introduit, l'implementation de l'antenne bi-bande dans une chaine de communication RFID. Les resultats de simulation montrent que l'antenne PIFA est un candidat interessant dans les applications multi-standards, parce qu'il premierement, presente un coefficient de reflexion faible, et adapte a l'excitation par cable coaxial. Deuxiemement, il y a une forme planaire permet une bonne distribution des densites de courant surfacique et par consequent un champ electrique intense aux extremites. Et finalement, son rayonnement est bidirectionnel si nous utilisons comme substrat l'epoxy, et omnidirectionnelle sans substrat (aire). Dans le futur, nous pensons a concevoir une antenne PIFA sur le polyethylene, avec un plan de masse planaire et par consequent une optimisation de l'antenne du tag adapte a l'impedance de la puce memoire.

Book Synopsis Planar Antenna by : Praveen Kumar Malik
Download or read book Planar Antenna written by Praveen Kumar Malik and published by Nova Science Publishers. This book was released on 2021 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book focuses on recent advances in the field of planar antenna design and their applications in various fields of research including space communication, mobile communication, wireless communication, and wearable applications. Planar antennas are also used in medical applications including microwave imaging, medical implants, hyperthermia treatments, and wireless wellness monitoring. However, most of these applications still use bulky antenna systems which hamper their efficiency and applicability despite high application potential. The primary objective of recent antenna research is the reduction in size and complexity. Students, scholars and researchers are used to doing mathematical modelling and pattern measurements in simulated environments only. Our aim is to show academic and industry researchers as well as advanced students and lecturers in electronics, electrical and instrumentation engineering how to do measurements in real-world environments. This book will present planar antenna design concepts, methods, and techniques to enhance performance parameters, as well as applications for IoTs and device-to-device communication. We will provide the latest techniques used for the design of antennas in terms of their structures, defected ground, MIMO, and fractal design. This book will also address the specific steps to resolve issues in designing antennas and how to design conformal and miniaturized antenna structures for various applications"--
Book Synopsis Quantum Communications and Cryptography by : Alexander V. Sergienko
Download or read book Quantum Communications and Cryptography written by Alexander V. Sergienko and published by CRC Press. This book was released on 2018-10-03 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: All current methods of secure communication such as public-key cryptography can eventually be broken by faster computing. At the interface of physics and computer science lies a powerful solution for secure communications: quantum cryptography. Because eavesdropping changes the physical nature of the information, users in a quantum exchange can easily detect eavesdroppers. This allows for totally secure random key distribution, a central requirement for use of the one-time pad. Since the one-time pad is theoretically proven to be undecipherable, quantum cryptography is the key to perfect secrecy. Quantum Communications and Cryptography is the first comprehensive review of the past, present, and potential developments in this dynamic field. Leading expert contributors from around the world discuss the scientific foundations, experimental and theoretical developments, and cutting-edge technical and engineering advances in quantum communications and cryptography. The book describes the engineering principles and practical implementations in a real-world metropolitan network as well as physical principles and experimental results of such technologies as entanglement swapping and quantum teleportation. It also offers the first detailed treatment of quantum information processing with continuous variables. Technologies include both free-space and fiber-based communications systems along with the necessary protocols and information processing approaches. Bridging the gap between physics and engineering, Quantum Communications and Cryptography supplies a springboard for further developments and breakthroughs in this rapidly growing area.

Available in PDF, EPUB and Kindle. Book excerpt: At the age of twenty-eight, Marty Ellis is still a bachelor who graduated with a major in journalism and a minor in photojournalism. He enjoys his life with various girlfriends while knocking back drinks in bars, going out to dinner, and rolling in the sheets. Yet inevitably, he grows tired of these surface-level-only feelings, shells out his standard goodbye speech, and moves on. However, using only his body and saying sayonara to his love lifeaEUR(tm)s revolving door is not how he wants to live for the rest of his life. How will he ever know what true love feels like if he doesnaEUR(tm)t ascertain how to actually give it? In what way will he begin to be able to discover the whole package that runs beneath the surface of a woman? Unexpectedly, Marty is blindsided when his best friend invites him to leave New Jersey for a weekend trip. Lauren Morris is a beautiful thirty-two-year-old woman who, after graduating at the age of twenty-one with a masteraEUR(tm)s degree in business, took a huge leap of faith and purchased an old farmhouse in Vermont. After ten years of hard work and sweat equity, she has transformed it into a beautiful inn that has become extremely lucrative. But winter is fast approaching, and she is dreading that feeling of loneliness that is connected to darkened afternoons and long, empty nights. Will a man ever enter her life? One that she could love and perhaps be with until death due them part? After meeting Marty, Lauren begins to consider if this man might be the one she has been waiting for her whole life. But then again, she is older than he is; long distance relationships hardly ever work out; and sudden heartbreaking unforeseen events rock both of their worlds. And if they do fall in love, which one of them will have to make the ultimate sacrifice and give up what theyaEUR(tm)ve worked so hard to achieve in order to be together? With so many changes causing so many challenges, will they get through them together, or will one push the other away?
