Advancement of Metamaterials-Based Antennas (Metantennas): From Hype to Reality
Since the late 1990s, metamaterials have sparked significant theoretical research, fundamentally transforming our understanding of electromagnetic (EM) theory. The promise of metamaterials has fueled anticipation of breakthroughs, especially in antenna technology. However, translating these novel physical concepts into practical technologies and real-world applications has proven challenging, primarily due to the stringent and unique requirements of […]
