Introduction

With the rapid development of electronic technology, mobile communication and satellite communication, electromagnetic interference (EMI) or Radio Frequency Interference (RFI) has received global scientific attention to ensure unperturbed performance of electronic items and to avoid any adverse effect on human health. EMI is one of the main factors that weaken electronic system performance and is considered as a modern form of environmental pollution.

Many efforts have been made to reduce EMI due to industrial regulations. With the expansion of the IT industry, microwave absorbing materials (MAMs) and EMI shielding materials have received considerable interest to improve the resistance of smart devices to EMI.

This book presents a comprehensive review of the recent developments in EMI shielding and the design of microwave absorbing materials. Chapters cover the basic mechanism of shielding and radiation absorption, measurement procedures, factors affecting the shielding and different materials for shielding and absorption (e.g. MWCNT, conjugated polymers, graphene, MXene based hybrid materials, Carbon foam, graphene based thermoplastic polyurethane nanocomposites, carbon-carbon composites, nano ferrite composites and conducting Ferro fluids). An analysis of EMI shielding using fillers composed of different materials is also presented.

In addition, key issues and current challenges to achieve better shielding and absorption performance for various materials are explained, giving the readers a broader perspective of the subject.

The book is suitable as a detailed reference for students in technology, electronics engineering and materials science courses, and professionals working on materials for designing EMI shielding mechanisms.

Audience:

Students of B. Tech / M. Tech / Engineering programs, Researchers and professional engineers working with nanomaterial composites for the design of shielding mechanisms in electronic devices

Foreword

Present book reflects the importance of EMI shielding in the field of functional microwave materials being relevant to material science and electrical and electronics engineering and ever increasing with the expansion of electronics, mobile communications and satellite communications. It is culmination of the hard work undertaken by the team under leadership of Dr. Dhawan over a long period of time and with great perseverance.

The book “Smart Materials Design for Electromagnetic Interference Shielding Applications”, comprises 12 chapters and covers the gamut comprising shielding performance and properties of the light weight carbon composite foams, synthesis and EMI shielding properties of carbon based nanostructures (CBNS) reinforced polymer nanocomposites, microwave absorption properties of graphene and its polymer nanocomposites, microwave absorption properties of graphene and its derivatives based nanocomposites and their composites with polyurethane and metal oxides, conjugated polymer and their composites viz. PEDOT and its composites with MWCNT, grapheme and graphene and graphene/strontium ferrite hybrid. Shielding properties of polypyrrole and polypyrrole-fly ash composites; polyaniline and polyaniline-carbon fiber composites and polyaniline-toluidine copolymer composites with carbon fiber are also elaborated in the book. Synthesis, shielding behavior and dielectric attributes of 2D materials such as graphene layered MoS2, nitrides, black phosphrous and MXenes, gamma ray shielding behavior of industrial waste like red mud in designing geopolymershave been discussed in carefully formatted chapters. The core ideas underlying various designs of microwave shield and their characterization essential to design a nearly perfect shield using different materials, methods and approaches are presented in an interesting manner. This book may serve as an important reference not only for professionals engaged in designing instruments for characterization and commercial microwave materials but for researchers cutting across disciplines interested in microwave materials and measurement methods. Written in a lucid manner with a sense of continuity, the book will surely be able to establish and sustain the interest in the field of Electromagnetic Interference with numerous applications.
