With the exponential rise of wireless devices, the electromagnetic interference (EMI) phenomenon affects the performance of these devices. Hence, it is critical to investigate various approaches to hinder the EMI effects. One of the most popular techniques to reduce EMI is to design and deploy microwave absorbers. This book presents the design requirements of novel electromagnetic wave shielding materials for modern commercial devices. A detailed in-depth analysis of the material synthesis with numerous practical case studies are presented in this book. The principles of microwave characterization of these materials are also explored. The definitions and procedural methods to characterize the shielding effectiveness are also presented. The practical use of polymer nanocomposite prepared by MWCNT, SWCNT, nanofibers, graphene and various ferrites in the polymer matrix is discussed. Practical use-case scenarios of design processes of various polymers along with general nanomaterials, carbon nanomaterials, inorganic magnetic nanoparticles, are also investigated. Lastly, alternate shielding methods are reported in the book.

This book bridges the gap between the conventional technology based on microstrip transmission line and futuristic technology based on Spoof Surface Plasmon Polariton-based transmission line. This book covers in detail, the study of different components such as filters, power dividers and antennas, etc., using Spoof Surface Plasmon Polariton. This book also focusses on the study of SSPP technology for biomedical applications. Textile and Flexible antennas are gaining popularity these days because of their applications in defence and daily use gadgets. These important aspects are also studied in this book using SSPP technology.

This book presents up-to-date information about WLAN antenna designs for students, researchers, and professionals who want to design radiating systems to be deployed for practical coverage. Thereby a detailed discussion on gain enhancement with the latest high-gain antenna designs is requisite while describing WLAN antennas.

Presents state-of-the-art information on the various types of semiconductor phase shifters, and explains why different types hold tremendous potential for future phased arrays.
