Aviation industry worldwide faced a tremendous challenge in increasing the laser attacks on aircraft. Such laser interference incidents have rapidly increased in numbers due to the recent ease of access to powerful, cheap, and portable lasers over the internet. Laser illuminations in aviation pose serious safety and security risks with significant implications to both air passengers and flight crew. The laser illumination risks create a new regulatory and policy need that can further stretch the existing limited resources and budgets to deal with this serious concern. Recently, Lamda Guard developed metaAIR, a dielectric (non-metallic) optical metamaterial filter which has been scientifically engineered to provide laser protection. It has been created from polymer materials using nano-patterned designs which are engineered to interact with incoming light, to block and deflecting it while offering transparency and superior angle performance. However, the current metaAIR prototypes suffers from the glare effect. Here, we are proposing an nanofabricated absorbing porous layer on metaAiR surfaces to mitigate the glare effects based on Glancing Angle Deposition (GLAD) technique.
