Ultranarrow-Band Wavelength-Selective Thermal Emission with Aperiodic Multilayered Metamaterials Designed by Bayesian Optimization.
Atsushi Sakurai,Atsushi Sakurai,Kyohei Yada,Tetsushi Simomura,Shenghong Ju,Shenghong Ju,Makoto Kashiwagi,Hideyuki Okada,Tadaaki Nagao,Tadaaki Nagao,Koji Tsuda,Koji Tsuda,Junichiro Shiomi,Junichiro Shiomi +13 more
TL;DR: The computationally designed an ultranarrow-band wavelength-selective thermal radiator via a materials informatics method alternating between Bayesian optimization and thermal electromagnetic field calculation and the resulting optimized structure is an aperiodic multilayered metamaterial exhibiting high and sharp emissivity.
Journal ArticleDOI
Resonant frequency and bandwidth of metamaterial emitters and absorbers predicted by an RLC circuit model
TL;DR: In this paper, a resistor-indicator-capacitor (RLC) circuit model is developed to describe the magnetic resonances inside the structures of metamaterial thermal emitters and absorbers.
Journal ArticleDOI
Perfect infrared absorber and emitter based on a large-area metasurface
Yuki Matsuno,Atsushi Sakurai +1 more
TL;DR: In this paper, an aluminum and ceria-based metasurface that exhibits nearly perfect emission/absorption in the infrared region was designed, and it was succeeded in fabricating the proposed metal-insulator-metal structures in the meter scale via photolithography and wet etching.
Journal ArticleDOI
Computational design for a wide-angle cermet-based solar selective absorber for high temperature applications
TL;DR: In this article, a solar selective absorber with tungsten-silica (W-SiO 2 ) cermet was designed for high temperature applications by using a characteristic matrix method and a genetic algorithm.
Journal ArticleDOI
