    报告题目:Measurement of Near-Field Thermal Radiation between Two Surfaces

    时间:7月12号上午11:00

    地点:动力楼J619

    报告内容简介:

 

  Near-field thermal radiation occurs when two objects are located closer than the characteristic wavelength of thermal radiation determined by Wien’s displacement law. At such small vacuum gap distances, the radiative heat transfer can exceed that between two blackbodies (i.e., Stefan-Boltzmann law) by several orders of magnitude. Despite abundant theoretical works, experimental demonstration of the near-field thermal radiation between flat surfaces is rather limited. One of the main challenges is maintaining a nanogap between planar surfaces with a large area. To overcome this issue, focus has now shifted to controlling the near-field thermal radiation via the introduction of nanomaterials instead of further reducing the vacuum gap distances. This presentation will address recent progress on control of the near-field thermal radiation at experimentally achievable vacuum gap distances by modifying the coupling nature of surface plasmons in nanomaterials.
