Abstract

The use of the natural materials instead of conventional materials as electromagnetic absorbers promotes environmental sustainability, cost-effectiveness, and ease of accessibility. Furthermore, these materials may also be designed as absorbers and as reinforcements in building materials in a lightweight form. The absorbing ability of composite materials can be customized based on the chosen fillers. Specifically, magnetic and dielectric fillers can be incorporated to improve the absorption of a composite material compared to traditional materials. This work aims to review recent developments of electromagnetic absorbers enabled by nanocomposites, metamaterial and metasurface-based, as well as green composite alternatives. First, the background concepts of electromagnetic wave absorption and reflection will be presented, followed by the assessment techniques in determining electromagnetic properties of absorbing materials. Next, the state-of-the-art absorbers utilizing different materials will be presented and their performances are compared. This review concludes with a special focus on the future perspective of the potential of metamaterial based nanocellulose composites as ultrathin and broadband electromagnetic absorbers.

Summary

INTRODUCTION

The development of wireless technologies with the particular aim at achieving higher communication throughput and wider bandwidths for high-speed communication have been developed rapidly to accommodate consumers’ needs. Several reviews have reported electromagnetic wave absorber materials based polymer composites [4] and [3] and metamaterial structures focused on the optical frequencies [6]. A review of the theoretical aspects of absorption and its assessment techniques will be presented, followed by the recent developments of nanocomposite absorbing materials, metamaterial and metasurface-based absorbers and green composite absorbers, and applications. The recent development of emerging absorbing materials/techniques such as nanocomposites and metamaterial-based absorbers will be discussed This is followed by the presentation of the recent methods towards enhancing microwave absorption based on alternative green and organic materials in electromagnetic absorption. Its production methods and potential applications will be discussed, prior to the discussion on the future perspective of such electromagnetic absorbing material
