The History of Metamaterials

Metamaterials are special structures made of tiny components that give them unique electromagnetic properties not found in nature. One key feature is a negative refractive index, which enables technologies like "superlenses" for ultra-detailed imaging and "invisibility cloaks." The concept began when Sir John Pendry theorized special rings (SRRs) that could manipulate electromagnetic waves. Later, Sheldon Schultz and David Smith proved this idea with real experiments. Since then, research on metamaterials has rapidly expanded, covering everything from microwaves to visible light. In this talk, Professors Pendry and Smith will share their experiences and discuss how metamaterials have shaped science and technology over the past 25 years.
