Abstract

This grant will support research that explores how mechanically morphable and modular assemblies can be integrated with optical metamaterials to enable new ways to control radiant heat. In recent years, scientific application of origami – transforming flat surfaces into complex 3D shapes – has expanded the concept to a range of designs that can fold, twist, or otherwise morph into different shapes on demand. These…
