This book focuses on elementary concepts of both radio frequency energy harvesting (RFEH) and wireless power transfer (WPT), and highlights their fundamental requirements followed by recent advancements. It provides a systematic overview of the key components required for RFEH and WPT applications and also comprehensively introduces the pioneering research advancements achieved to date. The state-of-the-art circuit design topologies for the two different applications are presented mainly in terms of antenna operating frequencies, polarization characteristics, efficient matching network circuits, rectifier topologies, and overall rectenna systems. The book serves as a single point of reference for practicing engineers and researchers searching for potential sources and elements involved in the RFEH system as well as in the WPT system, and need rapid training and design guidelines in the following areas:

Free Download Marissa J. Moorman, "Powerful Frequencies: Radio, State Power, and the Cold War in Angola, 1931-2002 "
English | ISBN: 082142369X | 2019 | 240 pages | PDF | 3 MB
Powerful Frequencies details the central role that radio technology and broadcasting played in the formation of colonial Portuguese Southern Africa and the postcolonial nation-state, Angola. In Intonations, Marissa J. Moorman examined the crucial relationship between music and Angolan independence during the 1960s and ’70s. Now, Moorman turns to the history of Angolan radio as an instrument for Portuguese settlers, the colonial state, African nationalists, and the postcolonial state. They all used radio to project power, while the latter employed it to challenge empire.

The book emphasizes both practical problem solving and a thorough understanding of fundamentals, aiming to realize the complementary relationship between practice and theory. Though the author emphasize wireless radio channels, the fundamentals that are covered are useful to different channels – digital subscriber line, coax, power lines, optical fibers, and even Gigabit serial interconnection.

Free Download Radio-Frequency Quadrupole Accelerators: From Protons to Uranium Ions (Particle Acceleration and Detection) by Chuan Zhang
English | November 19, 2023 | ISBN: 3031409663 | 186 pages | MOBI | 28 Mb
This book guides readers into the realm of particle accelerators, which have served as indispensable tools for fundamental research, energy development, medical therapy, industrial applications, national security, etc., since 1924. Towards a new generation of high power proton and ion accelerators, challenges often come from space charge effects, which are most pronounced in low-velocity beams. This book focuses on Radio-Frequency Quadrupole (RFQ) accelerators, one of the most popular front-end structures for accelerator facilities, and their beam physics. Uncovering the limitations of the classic design methods, novel approaches to achieve efficient RFQ accelerators with high beam quality will be presented. In addition, new ideas for possible future developments, such as how to realize long RFQs with high performance and how RFQs can be applied for much higher beam-velocities to shorten large-scale accelerators, will be introduced. To provide a general overview of the research and development of RFQs accelerating particle species from protons to uranium ions, this book uses over 10 real examples developed or proposed in the twenty-first century for various facilities of different dimensions (from large scale e.g. a collider to small scale e.g. university experimental setups). With its rich content and comprehensive scope, this book is an invaluable reference for researchers and graduate students interested in RFQ accelerators and the intricacies of space charge physics in low-velocity beams.

Free Download Radio Free Boston: The Rise and Fall of WBCN By Carter Alan, Steven Tyler
2013 | 352 Pages | ISBN: 1555537294 | EPUB | 5 MB
Blaring the Cream anthem "I Feel Free," WBCN went on the air in March 1968 as an experiment in free-form rock on the fledgling FM radio band. It broadcast its final song, Pink Floyd’s "Shine On You Crazy Diamond," in August 2009. In between, WBCN became the musical, cultural, and political voice of the young people of Boston and New England, sustaining a vibrant local music scene that launched such artists as the J. Geils Band, Aerosmith, James Taylor, Boston, the Cars, and the Dropkick Murphys, as well as paving the way for Bruce Springsteen, Tom Petty, U2, and many others. Along the way, WBCN both pioneered and defined progressive rock radio, the dominant format for a generation of listeners. Brilliantly told by Carter Alan–and featuring the voices of station insiders and the artists they loved–Radio Free Boston is the story of a city; of artistic freedom, of music and politics and identity; and of the cultural, technological, and financial forces that killed rock radio.
