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.

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 DegreesC,
which scientists view as a threshold presaging catastrophic
run-away processes.

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 levitation is commonly associated with transport
applications, principally 'MagLev' trains. However, the technology
has many potential applications across engineering, particularly
where there is a requirement to improve efficiency of electrical
products and devices, propelled by the desire to minimise
frictional and bearing losses and ohmic losses in conductors, which
are the major causes of machine inefficiency. Fundamentals of
Electromagnetic Levitation: Engineering sustainability through
efficiency is an introductory text encompassing the enabling
electrical technologies associated with magnetic levitation,
electrostatic suspension, diamagnetic levitation and
superconduction, high frequency magnetic levitation, high frequency
electric suspension, and levitation using microwave pressure. It
aims to make aspiring and existing electrical engineers aware of
the efficiency implications of frictionless machines and hence, of
how important this may be in a post-fossil fuel world in which the
energy available from renewable sources is strictly limited.
