    Visualization Of Ultra-Thin Semi-Transparent Metallic Films By Wave Simulations And Ray-Tracing Rendering




    Plasmonic color generation describes structural color arising from resonant interaction between visible light and metallic nanostructures, causing selective frequencies of light to be scattered and/or absorbed [Kristensen et al. 2017; Sun and Xia 2003]. The perceived color from such metallic nanostructures is highly dependent on viewing angle and the color appearance can change with color of the viewing background. Plasmonic color generation is a rapidly emerging research area with potential advantages over conventional pigment printing technology including higher printing resolution and robustness, greater compatibility for integration and functionalization, and reduced resource requirements [Mudachathi and Tanaka 2017; Zhu et al. 2017]. Structural color from plasmonic nanostructures has already been used to improve security measures in currency notes and credit cards [Lee et al. 2018]. 

    Achieving desired structural coloration using nanostructures requires bottom-up design in which the electromagnetic properties of nanostructures are simulated and then extrapolated to model their visual appearance. Computer graphics technology can be used to provide visualization of the optical properties of nanostructures on large scales [Auzinger et al. 2018; Musbach et al. 2013; Zhu et al. 2009]. In this work, we propose to use finite-difference time domain (FDTD) simulations to model electromagnetic interaction of visible light with nanostructures and create physical-based material models to visualize their appearance by ray-tracing rendering.
