Abstract
Description
This work utilizes predictive modeling techniques to guide and inform metamaterial design for heat management solutions and thermal radiation control. Specifically, micro- and macro-scale polyethylene-based solutions are proposed for passive and active thermal camouflage. A micro-scale post design is proposed for highly-tunable infrared emissivity based on varying unit cell geometrical configurations. Actively modulating these micro-features through lateral straining of up to 3% allows for redshifting the emissivity spectrum by up to 0.5 µm. Macroscale lenticular lens designs allow for a more passive form of camouflage due to its emissive stability for a range of configurations (e.g., single and sandwiched structures, increasing lens radii and height). Overall, the proposed metamaterial designs allow the tailoring of optical properties to improve thermal radiating performance.
