Abstract
Metamaterial absorbers are artificial materials that satisfy optical thicknesses and geometrical thinness simultaneously. By leveraging the characteristics of these metamaterials, we can artificially control the direction of heat flow on spaces or objects. For instance, we demonstrated the ability to generate artificial heat flow across an object or space by controlling the metamaterial arrangement, thereby achieving thermoelectric power generation in a uniform thermal radiation environment. This technology allows us to achieve energy harvesting while simultaneously achieving environmental cooling through non-radiative cooling. Additionally, we introduce the application of this metamaterial thermoelectric conversion technology to optical wireless powering.
