Mechanical Optimization of Optical Nanomultilayers
Abstract
The overarching research objective is to design, synthesize and test, mechanically optimized highly transparent nanomultilayers (NMs). The proposed research aims to design multifunctional NMs where both optical and mechanical properties are optimized for transparency in the UV to mid-IR range. The scientific objectives will be pursued by employing novel synthesis techniques in conjunction with methodology driven by optical optimization algorithms, which provide the foundational optical tunability. Recent work by the Hodgegroup (unpublished) has shown for the first time, the relationships between the mechanical properties of periodic and optically optimized NMs under different deformation modes. Therefore, our proposed work is guided by fundamental science for optimizing the mechanical behavior for new high-performance, long-lasting optical engineering materials that will reduce the cost of ownership of essential equipment needed for DoN missions. More specifically, this project aims to bridge a significant knowledge gap regarding the deformation of non-metallic multilayers by focusing on a subset of important optical NM materials. Directing the research towards transparent optical multilayers provides a finite selection of materials with a large window of transmission from UV to mid-IR wavelengths and beyond. These materials have broad Naval applications such as transparent load-bearing armor, high durability windows and face shields, sensor windows, transparent windows that are scratch resistant and self-cleaning, as well as windows with spectral selectivity.Approved for Public Release
