Adaptive Surfaces with Tunable Spectrally Selective Reflection and Emission of Infrared Radiation
Abstract
The principal motivation of this proposal is to investigate the interaction of infrared radiation with aerospace materials in extreme environments. In this context, layered materials with adaptive response to infrared radiation can play an important role in thermal management in aerospace materials and in extreme environments. In this project, the research will investigate adaptive surfaces with broadband spectrally selective reflectivity and emissivity that can be tuned by external stimuli. In one aspect of this proposal, the research aims to obtain in the (1.0 - 3.0 ?m) spectral range an adaptive surface that has low emissivity/high reflectivity at room temperature, whereas high emissivity/low reflectivity at high temperatures. Also in this project, the research will explore a design technique for adaptive materials (including VO2) to obtain surfaces for radiative heat transfer problems that cannot be attained with parametric studies and intuitive expectations. A topology technique using an adjoin-based design method in this project will be investigated for adaptive materials to achieve novel spectrally selective filters.
