Making it big: Metamaterial applications a step closer to reality

The use of a fabrication technique borrowed from the semiconductor industry brings metamaterial applications a step closer to reality. Artificial materials engineered to have properties not found in nature, such as a negative refractive index are engineered to interact with light and sound waves in ways that natural materials cannot. They thus have the potential to be used in exciting new applications, such as invisibility cloaks, high-resolution lenses, efficient and compact antennas, and highly sensitive sensors.
