Insights into Civilian Electromagnetic Absorption Materials: Challenges and Innovative Solutions

Abstract

AbstractThe emergence and widespread adoption of fifth‐generation wireless technology in civilian sectors have advanced the information revolution, while simultaneously leading to a variety of negative impacts. Foremost issues in the civilian domain include electromagnetic (EM) pollution, interference, and the inefficient use of EM energy. Despite growing global awareness, progress in devising effective solutions is sluggish, underlining the complexity of these issues. The delay in addressing EM concerns arises from several factors, including a considerable gap in comprehensive understanding and the absence of a unified stance on these critical issues. Moreover, the emergence of new challenges like EM interference and energy inefficiency indicates a clear need for innovative ideas and approaches. Addressing these civilian issues extends beyond the inherent properties of EM absorbers, requiring combination of tailored macro‐structural designs and external energy field management for a comprehensive solution. This situation emphasizes the urgent need for diverse strategies and creative thinking to navigate the challenges posed by the civilian EM issues. This perspective underscores these identified challenges and systematically proposes practical approaches to each, aiming to foster both conversation and action in this crucial area. The insights provided are expected to substantially aid in confronting and alleviating these pressing EM concerns.
