Book Description
This book offers a comprehensive overview of design and analysis of microwave devices and circuits for 5G and beyond wireless communication systems. It focuses on modern microwave antennas, filters, metamaterials, and MIMO systems. It includes a design approach based on Artificial Intelligence and the practical use of microwave devices and circuits in commercial, medical, and military applications. Microwave Devices and Circuits for Advanced Wireless Communications: Design and Analysis explores the performance of microwave devices and circuits by highlighting the difficulties encountered by researchers and designers such as latency, interoperability, wireless coexistence, data streaming, safety, security, and privacy. The book explores the most important aspects of antenna design, including radiation pattern control, impedance matching with bandwidth improvement, and gain enhancement. It also examines different categories of metasurfaces, including frequency-selective surfaces (FSS) and electromagnetic bandgap (EBG) structures, and their distinct roles in antenna design. Additionally, the book examines concepts such as ultra-wideband (UWB) radar for 5G millimeter wave applications, and advanced techniques such as synthetic aperture radar (SAR), beam-forming, compressed sensing, and diffraction tomography for enabling high-resolution imaging across wider application areas. The authors also present an overview on applying machine learning (ML) techniques to advanced wireless communication for signal-processing tasks such as signal denoising, equalization, and modulation recognition. They then discuss the potential significance of UAV communication systems in achieving seamless connection, quality of service (QoS), as well as the difficulties and potential remedies involved in building dependable networks using UAVs. Throughout the book the authors offer a critical assessment of the strengths and limitations of each topic and approach presented, thus providing valuable guidance for future research in this exciting field. This book will be helpful for graduate students, researchers, and engineers working in the area of design and reliability of circuits for microwave and communication systems.

Book Description
Following the emergence of lasers and optical fibers, optical networking made its beginning in the 1970s with high-speed LANs/MANs. In the 1980s, when the bandwidth of intercity microwave links turned out to be inadequate for digital telephony, the technology for single-wavelength optical communications using SONET/SDH arrived as a saviour to replace the microwave links. However, single-wavelength links couldn't utilize the huge bandwidth (40 THz) of optical fibers, while the bandwidth demands kept soaring. This necessitated the use of wavelength-division multiplexing (WDM) for concurrent transmission over multiple wavelengths, increasing the available bandwidth significantly. Today, optical networking has become an indispensable part of telecommunication networks at all hierarchical levels. The book Optical Networks provides a graduate level presentation of optical networks, capturing the past, present and ensuing developments with a unique blend of breadth and depth. The book is organized in four parts and three appendices. Part I presents an overview and the enabling technologies in two chapters, Part II presents the single-wavelength optical networks in three chapters, while Part III deals with the various forms of WDM optical networks in four chapters. Finally, Part IV presents some selected topics in six chapters, dealing with a number of contemporary and emerging topics. Optical Networks provides a comprehensive all-in-one text for beginning graduate as well as final-year undergraduate students, and also allows R&D engineers to quickly refresh the basics and then move on to emerging topics.

Book Description
From January to July of 1862, the armies and navies of the Union and Confederacy conducted an incredibly complex and remarkably diverse range of operations in the Commonwealth of Virginia. Under the direction of leaders like Thomas “Stonewall” Jackson, George McClellan, Joseph E. Johnston, John Rodgers, Robert E. Lee, Franklin Buchanan, Irvin McDowell, and Louis M. Goldsborough, men of the Union and Confederate armed forces marched over mountains and through shallow valleys, maneuvered on and along great tidal rivers, bridged and waded their tributaries, battled malarial swamps, dug trenches and constructed fortifications, and advanced and retreated in search of operational and tactical advantage. In the course of these operations, the North demonstrated it had learned quite a bit from its setbacks of 1861 and was able to achieve significant operational and tactical success on both land and sea. This enabled Union arms to bring a considerable portion of Virginia under Federal control—in some cases temporarily and in others permanently. Indeed, at points during the spring and early summer of 1862, it appeared the North just might succeed in bringing about the defeat of the rebellion before the year was out. A sweeping study of the operations on land and sea, From the Mountains to the Bay is the only modern scholarly work that looks at the operations that took place in Virginia in early 1862, from the Romney Campaign that opened the year to the naval engagement between the Monitor and Merrimac to the movements and engagements fought by Union and Confederate forces in the Shenandoah Valley, on the York-James Peninsula, and in northern Virginia, as a single, comprehensive campaign. Rafuse draws from extensive research in primary sources to provide a fast-paced, complete account of operations throughout Virginia, while also incorporating findings of recent scholarship on the factors that shaped these campaigns. The work provides invaluable insights into the factors and individuals who shaped these operations, how they influenced the course of the war, the relationships between political leaders and men in uniform, and how all these factors affected the development and execution of strategy, operations, and tactics.
