MetaAir metamaterial film protects pilots from cockpit laser strikes
A metamaterial-based, laser-protection film called Lamda Guard metaAIR is designed to protect pilots against cockpit laser strikes.
Working with Airbus since 2014, Metamaterial Technologies (MTI; Dartmouth, NS, Canada) is close to commercializing a patented, metamaterial-based, laser-protection film called Lamda Guard metaAIR designed to protect pilots against cockpit laser strikes. The flexible, paper-thin, nearly transparent film is applied directly to any glass or plastic surface, like the inner surface of a cockpit windscreen, and selectively deflects specific wavelengths of light before they reach the interior of the aircraft.
Created from metamaterial polymer materials using lithographic and holographic nanopatterned designs with features as small as 5 nm, metaAIR materials can also incorporate silver nanoparticles, for example, to enhance plasmonic resonance and further control the electric and magnetic fields of a new structure. A multiphysics approach of patterning, stacking, and choosing the right background materials is used to create films in a scalable manufacturing process that deflect, block, enhance, or absorb electromagnetic radiation of a particular waveband. MTI's platform metamaterial technology can also be applied to protective eyewear, retractable visors, optical sensors, and even to enhance the accuracy of noninvasive medical devices at millimeter wavelengths (see www.gluco-wise.com).
