This book presents the applications of non-volatile CBRAM/MIM switching technology for electronically reconfigurable passive RF and microwave devices, together with theory and methods for application in rewritable chipless RFID tags. Conductive Bridging Random Access Memory (CBRAM) is a renowned and commercially used non-volatile memory concept. Having evolved over the past few decades, it is currently identified as an efficient non-volatile RF switching technology. This book presents recent research on this topic, focusing on the development of a new generation of low-cost non-volatile RF switches and their applications, demonstrating both high performance and flexibility of implementation. It includes the experimental realization of various prototypes of RF and microwave devices utilizing this technology, along with relevant analysis of mathematical and electrical models, and detailed discussions of future aspects. All devices presented are compatible with mass industrial production at an economically efficient budget through optimized fabrication steps, without the requirement of sophisticated “clean room” processes among them.

This book introduces readers to the physical design (layout) and design automation of Photonic Integrated Ciruicts (PICs) which is an essential building block of Electronic-Photonic Design Automation (EPDA). Proper PIC design automation and implementation of complex curvilinear shapes play a critical role in reliability, quality, and time-to-market of complex PIC products. The author starts by introducing some basic mathematical concepts used in implementation of photonic components, followed by a deep dive into implementation details of parameterized PIC components. The book introduces the industry-standard schematic driven layout flow and tries to simplify the concepts and implementations. The author conveys difficult concepts and advanced EPDA scripting/programming methodologies, using a simple language and coding examples. I have included Chap. 6 to introduce proper scalable software development methodology using SKILL++. Virtuoso is the tool used for the implementation of my designs and the Virtuoso CurvyCore mathematical engine is used to implement photonic devices’ physical design (layout). SKILL is the main scripting language used for code implementation. All the examples provided in the book are based on Generic Optical Process Design Kit (GoPDK), which is a generic optical PDK developed by Cadence Design Systems, Inc. to demonstrate their photonic solution capabilities.

This unique book brings together RF Engineering and Optical Integration in terrestrial fixed and mobile networks, space networks and sub orbital communication systems (Low Altitude Platforms and High-Altitude Platforms). It is written specifically to help optical engineers to understand RF engineering and RF engineers needing to understand the optical technologies used in fixed and mobile networks, including local and long-distance fiber, free space terrestrial optical point to links, earth to space and space to earth links and inter satellite and inter-constellation cross connect. The book shows you how to mix and match RF and optical efficiently and explains how to repurpose terrestrial RF and terrestrial optical for space deployment. You’ll learn how to decide whether to use an RF or optical link; how to calculate an RF and optical link budget; how to interface an optical signal to an RF bearer – and vice versa; how to multiplex RF and optical signals in guided and unguided media; and much more. This is a must-have book for practicing RF engineers, optical engineers, and planners of satcom and terrestrial networks, supply chain partners to 5G/satellite RF/optical integrations needing understanding of problems and solutions.

Enables students to understand power electronics systems, as one course, in an integrated electric energy systems curriculum. Power Electronics A First Course provides instruction on fundamental concepts related to power electronics to undergraduate electrical engineering students, beginning with an introductory chapter and moving on to discussing topics such as switching power-poles, switch-mode DC-DC converters, and feedback controllers. The authors also cover diode rectifiers, power-factor-correction (PFC) circuits, and switch-mode dc power supplies. Later chapters touch on soft-switching in dc-dc power converters, voltage and current requirements imposed by various power applications, dc and low-frequency sinusoidal ac voltages, thyristor converters, and the utility applications of harnessing energy from renewable sources. This textbook focuses on power electronic systems as one of the topics in an integrated electric energy systems curriculum consisting of power electronics, power systems, and electric machines and drives. This textbook follows a top-down systems-level approach to power electronics to highlight interrelationships between these subfields within this curriculum, and is intended to cover both the fundamentals and practical design in a single-semester course.

By proposing and forming a mobile manipulator for modern multi-floor buildings, A Robotic Framework for the Mobile Manipulator: Theory and Application helps readers visualize an end-to-end workflow for making a robot system work in a targeted environment. From a product-oriented viewpoint, this book is considered as a bridge from theories to real products, in which robotic software modules and the robotic system integration are mainly concerned. In the end, readers will have an overview of how to build and integrate various single robotic modules to execute a list of designed tasks in the real world, as well as how to make a robot system work independently, without human interventions. With references and execution guidelines provided at the end of each chapter, the book will be a useful tool for developers and researchers looking to expand their knowledge about the robotics and the robotic software. Single robotic modules and the system integration are then conducted on the Robot Operating System 2 (ROS2) and presented in remaining chapters as follows: in Chapter 2, a task-oriented approach is used to propose hardware and software modules for a robot system.
