Paper Abstract

The union of mico / nano electromechanical systems with metamaterials offers a new route to achieve reconfigurable devices which control the emission of energy. Here we propose and demonstrate the idea of metamaterial MEMS capable of modifying the emitted energy without changing the temperature. Rather our device only alters the spectral emissivity, thus realize a differential emissivity equivalent to a nearly 20-degree Celsius temperature change across the thermal infrared. We pixelate our device and thereby achieve a spatio-temporal emitter capable of displaying thermal infrared patterns up to speeds of 110 kHz. Our results are not limited to the thermal infrared band, but may be scaled to nearly any sub-optical range of the electromagnetic spectrum, and verify the potential of MEMS metamaterials to operate as reconfigurable multifunctional devices with unprecedented energy control capabilities.
