我们研究了双曲超材料的近场辐射热能传输特性。在很宽的带宽内，独特的电磁态的存在导致了超普朗克热能在由纳米间隙隔开的超材料之间的传递。我们考虑了用于中红外热工程的实用声子-极化子超材料，结果表明，尽管存在损耗、吸收和有限的晶胞尺寸，这种效应仍然存在。对于需要在近红外范围内进行能量转移的热光伏能转换应用，我们介绍了基于高熔点等离子体材料的高温双曲异质材料。我们的工作为双曲超材料高温辐射热能传递的实际应用奠定了基础。(C)2013年美国光学学会
We explore the near-field radiative thermal energy transfer properties of hyperbolic metamaterials. The presence of unique electromagnetic states in a broad bandwidth leads to super-planckian thermal energy transfer between metamaterials separated by a nano-gap. We consider practical phonon-polaritonic metamaterials for thermal engineering in the mid-infrared range and show that the effect exists in spite of the losses, absorption and finite unit cell size. For thermophotovoltaic energy conversion applications requiring energy transfer in the near-infrared range we introduce high temperature hyperbolic metamaterials based on plasmonic materials with a high melting point. Our work paves the way for practical high temperature radiative thermal energy transfer applications of hyperbolic metamaterials. (C) 2013 Optical Society of America
