Meta-materials are engineered materials with properties not found in nature. They manipulate electromagnetic waves and other phenomena by virtue of their structure rather than their chemical composition.
Reducing mass and improving structural integrity in spacecraft components to enhance performance and reduce launch costs.
These materials achieve their unique properties through a precise arrangement of sub-wavelength structures, often using periodic or aperiodic patterns at the nanoscale level. This allows for control over how light, sound, or even gravity interacts with them.
Manufacturing meta-materials requires advanced techniques such as lithography, etching, and deposition processes. These methods are complex and require high precision equipment.
The process involves designing the nano-scale structures using computational models, then fabricating these structures on a substrate through precise manufacturing techniques. The resulting material is then tested for its electromagnetic properties.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking and high-temperature processes.
