This book consists of three main parts: fundamental theory, design principles and methodology, and potential materials that can be applied to EM wave absorbers. In the theory part, this book provides the basics of electromagnetism, circuit and transmission line theory, EM wave propagation and reflection, and complex permittivity and permeability by electric polarization and magnetization of materials. In the design part, design methods are explained for various types of EM wave absorbers based on equivalent circuit models and simulation technologies. Starting from the traditional...

In an effort to overcome the spectral efficiency loss and high latency by half-duplex (HD), full-duplex (FD) has attracted extensive attention in industry and academia. With signal transmitted and received simultaneously over the same frequency, FD can approximately double the SE over HD. More than that, by enabling the capability of simultaneous transmission-and-reception for communication nodes, full duplex (FD) is a key enabler for many 5G techniques, including but not limited to integrated sensing and communication, low-latency relaying, concurrent bi-directional uplink and downlink...

This book covers the most recent, advanced methods for designing mixed-signal integrated circuits, for radiation-hardened sensor readouts (capacitive) and frequency synthesizers (quadrature, digitally controlled oscillators and all-digital PLL etc.). The authors discuss the ionizing radiation sources, complex failure mechanisms as well as several mitigation strategies for avoiding such failures. Readers will benefit from an introduction to the essential theory and fundamentals of ionizing radiation and time-based signal processing, with the details of the implementation of several...

This book introduces the fundamentals of physical layer security (PLS) and demonstrates how a variety of PLS techniques can be applied to improve the security of wireless communication systems. In particular, this book covers three security aspects of wireless communications. It includes secrecy, i.e., preventing eavesdroppers from intercepting information from transmitted wireless signals, covertness, i.e., hiding the transmitted signals themselves from malicious wardens and authentication, i.e., authenticating the identities of communicating entities. 

When discussing the secrecy...

This book studies the intersection between cryptography and AI, highlighting the significant cross-impact and potential between the two technologies. The authors first study the individual ecosystems of cryptography and AI to show the omnipresence of each technology in the ecosystem of the other one. Next, they show how these technologies have come together in collaborative or adversarial ways. In the next section, the authors highlight the coevolution being formed between cryptography and AI. Throughout the book, the authors use evidence from state-of-the-art research to look ahead at the...
