Summary form only given. Recent studies of thermal emission control have revealed many interesting phenomena. The influence of microstructures upon thermal emission, however, has not well been understood. In this paper, we report experimental results of thermal emission from a tantalum surface having a periodic array of microcavities. We have experimentally demonstrated that in the case of large aperture ratio, the effect caused by the modes in a cavity becomes dominant, while in the case of small aperture ratio, thermally excited SPP has more influence on thermal emission.
