This book covers the new field of straintronics, using strain switched nanomagnets for extremely energy-efficient computing, information processing, communication, and signal generation. Based on well-established CMOS technology, traditional electronics have two significant shortcomings: excessive energy dissipation and volatility, which is the inability to retain information after power has been switched off. Straintronics is more energy-efficient and non-volatile (but also more error-prone), allowing it to eclipse traditional electronics in niche areas that are increasingly attracting attention, such as image processing and probabilistic computing, computer vision, Machine Learning, neuromorphic networks, probabilistic computing, and belief networks.

The textbook presents basic concepts of signals and systems in a clear manner, based on the author's 15+ years of teaching the undergraduate course for engineering students. To attain full benefit from the content, readers should have a strong knowledge of calculus and be familiar with integration, differentiation, and summation operations. The book starts with an introduction to signals and systems and continues with coverage of basic signal functions and their manipulations; energy, power, convolution, and systems; Fourier analysis of continuous time signals and digital signals; Laplace transform; and Z transforms. Practical applications are included throughout. The book is also packed with solved examples, self-study exercises, and end of chapter problems.

The book is written as a textbook and exercise book. This means that you will be introduced to new areas through explanation or examples. To consolidate your knowledge and to check your learning and success, we recommend that you do the exercises. Sample solutions are available for most exercises: Each exercise has a unique name under which the solution can be found on the authors’ website. An integral part of this book is the PLC simulation software “PLC-lite”, which was developed by the authors especially for this course. You can download it free of charge from the authors’ website. This gives you the opportunity to intensively test a control system that conforms to the standards, regardless of limitations with real systems. The scope of commands, data types, structures, etc. has been selected in such a way that the special features of programming in instruction lists according to IEC 61131-3 can be easily understood using the exercises from this book. In addition, “PLC-lite” contains a large number of processes as animated simulations. This allows you to test your programs in a practical and safe manner and to study the behavior of the controlled processes (even under extreme conditions or “errors”). Your PC is thus both a programming device and PLC automation device as well as a “technical system”.

This book presents the key technologies of coherent optical wireless communication, covers topics such as beam coupling, signal optical polarization control and distorted wavefront correction. It discusses the principle of coherent optical communication and heterodyne detection conditions. In this book, the array coupling receiving technology and large aperture coupling technology are introduced to realize the spatial optical fiber coupling; simulated annealing algorithm, particle swarm optimization algorithm and SPO algorithm are used to control the polarization state of the signal beam; and the correction of distorted wavefront of the signal beam by adaptive optics technology and wavefront sensorless adaptive optics technology are analyzed, and the influence of beam mode on coherent detection performance is elaborated. Both theoretical deduction and experimental results are included in this book, which can help readers further understand the theoretical knowledge.

Authoritative resource covering preliminary concepts and advanced concerns in the field of IRS and its role in 6G wireless systems. Intelligent Reconfigurable Surfaces (IRS) for Prospective 6G Wireless Networks provides an in-depth treatment of the fundamental physics behind reconfigurable metasurfaces, also known as intelligent reflecting surfaces (IRS), and outlines the research roadmap towards their development as a low-complexity and energy-efficient solution aimed at turning the wireless environment into a software-defined entity. The text demonstrates IRS from different angles, including the underlying physics, hardware architecture, operating principles, and prototype designs. It enables readers to grasp the knowledge of the interplay of IRS and state-of-the-art technologies, examining the advantages, key principles, challenges, and potential use-cases. Practically, it equips readers with the fundamental knowledge of the operational principles of reconfigurable metasurfaces, resulting in its potential applications in various intelligent, autonomous future wireless communication technologies.
