Intelligent Reflecting Surface-Aided Physical-Layer Security : Springer : 9783031418112 : 3031418115 : 12 Oct 2023 : This book discusses the problems of  Physical Layer Security (PLS) in Intelligent Reflecting Surface (IRS)-assisted wireless networks. It also discusses the corresponding methods to solve these problems in a comprehensive style.  Furthermore, some potential challenges are well analyzed. This book is divided into 11 chapters.  Chapter 1 introduces the propagation characteristics of IRS-aided PLS communications. From Chapter 2 to Chapter 10, The authors mainly provide deep investigations of different PLS problems of  IRS-aided wireless networks, namely, directional modulation (DM) networks. Chapter 11 draws a conclusion and includes the future research directions. Researchers working in wireless communications, or advanced-level computer science or electrical engineering students, can learn about secure communication in the physical layer through our book.
