● A metamaterial is any material engineered to have a property that is not found in naturally occurring materials . ● They are made from assemblies of multiple elements fashioned from composite materials such as metals and plastics. ● Potential applications of metamaterials are diverse and include optical filters, medical devices, remote aerospace applications, sensor detection and infrastructure monitoring, smart solar power management, crowd control, radomes, high-frequency battlefield communication and lenses for high-gain antennas , improving ultrasonic sensors, and even shielding structures from earthquakes. ● Metamaterials offer the potential to create super lenses . Such a lens could allow imaging below the diffraction limit that is the minimum resolution that can be achieved by conventional glass lenses.
