The invisibility cloak in Harry Potter and the dreams of invisibility as a superpower are no longer fiction. With the invention of metamaterials, they are theoretically and experimentally possible in real life. Metamaterials — materials that are engineered to have properties that are not found in naturally-occuring materials — allow us to overcome physical limitations. Scientists around the world are researching metamaterials that can be used in diverse sectors, including healthcare, optical display, and military affairs. For example, metalenses, which can exceed the physical limitations of light, may facilitate leaps in biology and chemistry.The development of metamaterials has just begun, but their potential is limitless. In this talk, I will give a brief overview of metamaterials and metasurfaces: principles, applications and manufacturing methods towards their science-to-technology transition.
