Hyperbolic metamaterials (left) allow for chip-sized optical and infrared filters with custom designed optical filtering properties. These filters are much reduced in size compared to existing technologies. Such metamaterials allow for light weight, robust hyperspectral and multi-wavelength imaging systems.
Target Application: Hyperspectral and multispectral imaging on space-based, drones and UAVs, and hand-held devices.

Rigorous Coupled Wave and Modal Analysis design and modeling tools have been developed that allow for fast and accurate design and modeling of metamaterials. The tools have user friendly graphical user interfaces and materials datasets. This project has contributed to numerous SBIR/STTR and NASA ACT projects in the design and modeling of metamaterials.
Target Application: Sensor development (i.e., hyperspectral, multispectral, and polarimetric), chemical and biological sensing.

In our in-situ/real-time monitoring approach, for the first time, we demonstrated that the spectral characteristics of elastic wave propagation in a specially designed artifact with periodic internal structures can be used to monitor AM/3DP quality and process parameters. The unique aspect of our approach is that we monitor a geometrically simple artifact (as opposed to the actual build) representing the complexities of a build.
Target Application: Such artifacts we design are used to qualify the state of the printing machine, its processes and the quality of the material(s)
