Meta-materials (MM: materials beyond the imagination) have been largely confined to tricks in the lab because the required components of silver and gold are not well adapted to semiconductor manufacturing processes and too much of the material is lost. These MM have the ability to bend narrow wavelengths of light, sound, and seismic waves. They have been used to make objects seem to “disappear.” […]
Meta-materials are a new class of materials that have been engineered to have properties not found in nature. It is a multidisciplinary science made possible by the tools of nanotechnology. The name refers to “materials beyond the imagination.”
Deep in a cave you turn off your light and it is blacker than any night. You turn on your flashlight and the environment seems to suck the light out of it. That is kind of black that scientists have recently created. We sometimes need a surface that doesn’t reflect light and other magical materials.
