Spray-Coatable Metamaterials for Use as Narrow Bandpass Filters(1001-315)

Triton, together with our STTR partner, proposes to develop the theory and fabrication capabilities necessary to develop a metamaterials coating solution for mirror optics that is capable of passing a narrow spectral band in the long wave infrared (LWIR) spectrum for the purposes of stray light correction in interceptor sensors. In the Phase I program we will deliver both a mathematical description and physical samples of the metamaterials. Our solution, unlike other metamaterials approaches will able to be applied as a spray coating, making our proposed material very conducive to real-world applications. It is based on theoretical metamaterials structures that allow greatly reduced the fabrication complexity. Initial calculations show that our metamaterials are low-loss, unlike related approaches which use lossy metal structures at a high fill factor. We expect our coatings to be rugged and durable.
