均一な熱輻射環境におけるメタマテリアル熱電変換

抄録

We propose metamaterial thermoelectric conversion that can produce electricity even in a uniform thermal radiation environment. A metamaterial absorber attached on the one end of a thermoelectric device absorbs thermal radiation emitted from the surrounding media, creating a thermal gradient across a thermoelectric element. We experimentally determined that a thermal gradient of 0.14 K on the device was created in a uniform thermal radiation environment at 364 K.
