Metamaterials for electromagnetic wave manipulation: Advancements and future prospects

Abstract

Metamaterials, with their unique ability to alter electromagnetic waves, have ushered in a new era of scientific and technological advancements. By exerting precise control over the behaviour of waves, these materials provide revolutionary applications, such as improved imaging, sensing, and communication systems. By utilizing sophisticated production processes such as nanofabrication methods and additive manufacturing, scientists can create metamaterials with exceptional accuracy at the nanoscale. This enables the practical application of these materials in various industries. Nevertheless, despite their excellent capacity, metamaterials encounter substantial obstacles, such as scalability concerns, intricate fabrication processes, and material degradation. However, current research endeavors, especially in interdisciplinary domains, present hopeful resolutions to surmount these obstacles, facilitating groundbreaking progress in domains like 5G technology, telecommunications, and medical imaging. This review study provides a complete analysis of recent accomplishments, problems, and probable future directions in metamaterial research. It offers insights into how nanotechnology addresses challenges and influences the field of electromagnetic manipulation.
