Title: Reconfigurable room temperature metamaterial infrared emitter

The marriage of micro/nanoelectromechanical systems with metamaterials offers a viable route to achieving reconfigurable devices, which control the emission of energy. Here we propose and demonstrate the idea of a metamaterial microelectromechanical system (MEMS) capable of tailoring the energy emitted from a surface, without changing the temperature, but, instead, only altering the spectral emissivity. Our metamaterial achieves a range of emissivities equivalent to a nearly 20°C temperature change when viewed with a thermal infrared camera. We tessellate a surface with individually reconfigurable MEMS metamaterial pixels, thus realizing a spatiotemporal emitter capable of displaying thermal infrared patterns up to 110 kHz. Furthermore, our results may be scaled to nearly any sub-optical range of the electromagnetic spectrum, and validate the potential of MEMS metamaterials to operate as reconfigurable multifunctional devices with unprecedented energy control capabilities.
