| Outline of Final Research Achievements |
Recently, the advanced control of thermal radiation by using micro-nano structures is of interest. A breakthrough technique is necessary to drastically enhance the radiative heat transfer because the radiative heat transfer flux is generally limited by Planck's law.
In this study, we focused on the combination of a metal micro-cavity structure with near-field effect. As a result of experiment, 30 times greater radiative heat flux was demonstrated between parallel plates with micro-scale gap. This is the first experimental demonstration of near-field thermal radiation with micro-nano structures.
