Compact Slot Array Antennas for Wireless Communications

By: Alan J. Sangster

This book describes and provides design guidelines for antennas that achieve compactness by using the slot radiator as the fundamental building block within a periodic array, rather than a phased array. It provides the basic electromagnetic tools required to design and analyse these novel antennas, with sample calculations where relevant. The book presents a focused introduction and valuable insights into the relevant antenna technology, together with an overview of the main directions in the evolving technology of compact planar arrays. While the book discusses the historical evolution of compact array antennas, its main focus is on summarising the extensive body of literature on compact antennas. With regard to the now ubiquitous slot radiator, it seeks to demonstrate how, despite significant antenna size reductions that at times even seem to defy the laws of physics, desirable radiation pattern properties can be preserved. This is supported by an examination of recent advances in frequency selective surfaces and in metamaterials, which can, if handled correctly, be used to facilitate physics-defying designs. The book offers a valuable source of information for communication systems and antenna design engineers, especially thanks to its overview of trends in compact planar arrays, yet will also be of interest to students and researchers, as it provides a focused introduction and insights into this highly relevant antenna technology.

Electromagnetic Foundations of Solar Radiation Collection

A Technology for Sustainability

By: Alan J. Sangster

This text seeks to illuminate, mainly for the electrical power engineers of the future, the topic of large scale solar flux gathering schemes, which arguably represent the major source of renewable power available. The aim of the content is to impart, from an electromagnetic perspective, a deep and sound understanding of the topic of solar flux collection, ranging from the characteristics of light to the properties of antennas. To do this five chapters are employed to provide a thorough grounding in relevant aspects of electromagnetism and electromagnetic waves including optics, electromagnetic radiation and reception, aperture antennas and array antennas and the quantum electrodynamics aspects of optical absorption, as it relates to photovoltaic techniques. The principles developed in these chapters are then used to underpin and elucidate the main chapters on photovoltaic collectors, concentrated solar power collectors, satellite based collection systems and optical nantennas. To establish the novel and transformative renewable technologies, which civilisation will soon require, in order to achieve sustainability quickly and effectively, the availability of professional engineers and scientists with a thorough and commanding grasp of the fundamental science is an absolutely essential prerequisite. This book provides this for solar power generating systems.

Warming to Ecocide

A Thermodynamic Diagnosis

By: Alan J. Sangster

Despite scientific evidence that business-as-usual is unsustainable, there is a huge and widespread inertia to ‘greening’ the planet. Warming to Ecocide considers climate change from a thermodynamic perspective and asks whether market-driven organisations have carried us to the point of no return through the flawed economics of endless growth. Warming to Ecocide begins by exploring the thermodynamic origins of climate change. It demonstrates that equilibrium thermodynamics can provide full explanations for the basic processes of life such as photosynthesis and metabolism, and that non-equilibrium thermodynamics is close to providing an explanation for how life started. Armed with a solid appreciation of the power of thermodynamics, the second half of Warming to Ecocide discusses whether multinational corporations have convinced the public that climate change is insignificant and thereby neutered any all attempts by governments to espouse environmentally-friendly policies. It then goes on to offer strategies whereby mankind may avoid propelling the global average temperature above the pre-industrial level by more than 2°C, which scientists view as a threshold presaging catastrophic run-away processes.

Energy for a Warming World

A Plan to Hasten the Demise of Fossil Fuels

By: Alan John Sangster

Energy for a Warming World" challenges the commonplace notion that the amount of power which mankind can potentially harness from renewable resources is more than large enough to assuage future demand levels. By examining the renewable issue from an electrical engineering perspective, and exercising due regard for the limited capability of current and future electrical generation and transmission systems, this book attempts to provide more realistic statistics for the levels of power which could be extracted from sustainable resources in the critical time frame of 30 to 40 years. The engineering logic leads inexorably to the importance of taking a global outlook on the switch to renewable power supply and transmission – an outlook which has some surprising and uncomfortable ramifications for mankind. "Energy for a Warming World" provides a new perspective on renewable resources for academics and researchers in environmental or electrical power engineering, as well as to students in related areas.

Parasiticide Screening

Volume 2: In Vitro and In Vivo Tests with Relevant Parasite Rearing and Host Infection/Infestation Methods

By: Alan A. Marchiondo,Larry R. Cruthers,Josephus J. Fourie

Parasiticide Discovery: In Vitro and In Vivo Tests with Relevant Parasite Rearing and Host Infection/Infestation Methods, Volume Two presents valuable screening methods that have led to the discovery of the majority of parasiticides commercialized in the animal health industry. As much of the knowledge of parasiticide discovery methods is being lost in the animal health industry as seasoned parasitologists retire, this book serves to preserve valuable methods that have led to the discovery of the majority of parasiticides commercialized in animal health, also giving insights into the in vitro and in vivo methods used to identify the parasiticide activity of compounds. - Addresses current issues of resistance, along with combination uses for resistant parasites - Presents useful, authoritative information (chemical, pharmaceutical, clinical, etc.) for the pyrantel family of compounds - Includes a discussion on screening methods in combination therapies - Provides cutting-edge material for an evolving area of scientific discussion - Includes in vitro and in vivo screens and parasite maintenance and culture methods

Australia 63

Australia 63

By: Alan Ross

Alan Ross (1922-2001) - distinguished poet, travel writer, and editor of London Magazine - also managed to excel in the role of cricket correspondent for the Observer, in which capacity he followed England/MCC on tours of Australia, South Africa and the West Indies. In the book-length accounts he published of these tours, his lifelong love of the game found glorious expression. Australia 63 offers Ross's account of an Ashes series that pitted the England XI led by Ted Dexter against Richie Benaud's host side. On paper England had talent to spare, including the recall to the team of ordained minister David Sheppard, and the renowned bowling attack of Fred Trueman and Brian Statham. But Benaud's Australian side had strength in depth too. Both captains were expressly committed to playing entertaining cricket. The reality, however, did not quite live up to the billing.
