Abstract

"Electromagnetic absorbers and emitters have been attracting interest in lots of fields, which are significantly revitalized because of the novel properties brought by the development of the metamaterials, the artificially designed materials. Metamaterials broadens the approaches to design the electromagnetic absorbers and emitters, making it possible to obtain the perfect absorption or emission at the wavelengths covering a wide range. Metamaterial absorbers and emitters are promising for various applications, including solar thermal-photovoltaics and thermal-photovoltaics for energy harvesting, chemical and biomedical sensors, nanoscale imaging and color printing. This work focuses on three aspects (materials, structures and design methods) to improve the experiment realizations of visible and infrared absorbers and emitters. Firstly, this work investigates simple structures based on aluminum and tungsten materials for the metamaterial absorber and emitter, which results in the realization of the all-metal visible color printing with square resonators and wavelength selective mid-infrared absorber (emitter) with cross resonators, respectively. Secondly, we explore the thermal emission properties of the quasi-periodic metal-dielectric multilayer metamaterials, which show the ability of engineering emissivity by different lattice structures. Finally, this work demonstrates the use of micro-genetic algorithm to realize efficient design and optimization for broadband metasurface absorbers, as well as wavelength-selective metasurfaces with giant circular dichroism. This work is believed to facilitate the development and application of metamaterial absorbers and emitters"--Abstract, page iv.
