手性超材料和双曲超材料近场热辐射研究

Near-Field Radiative Heat Transfer Between Chiral Metamaterials and Hyperbolic Metamaterials

不同材料间由于共振频率不匹配使得其表面波不能耦合,进而使得近场辐射换热强度较相同材料间有所降低。超材料的发展为近场热辐射的可调控性开辟了新的通道。本文利用涨落耗散定理和并矢格林函数研究了两种不同的电磁超材料间近场辐射特性,通过调节两种材料的强可调控特性来调节近场辐射热流,克服由于共振频率不匹配产生的不同材料间辐射换热降低的问题。

Due to the resonance frequency mismatch between different materials,the surface wave cannot be coupled,and thus the near-field radiative heat transfer is lower than that of the same material.The metamaterials are introduced to find a new channel to tune the near-field thermal radiation.In this paper,we investigate the near-field radiative heat transfer between two different electromagnetic metamaterials overcome the reduction of the heat flux between two different materials.
