In the past decades, researchers developed various approaches to mimic “blackbody” behavior in different spectral regions from visible to microwave domain. In classic microwave electromagnetic (EM) area, EM wave absorbers have been explored for a long time, which can be generally categorized into narrow band resonant absorbers and broadband nonresonant absorbers. While there is great interest in achieving ‘black’ materials exhibiting large broadband absorption using optically thick materials, it is still challenging to realize ultra-thin/small “blackbodies” on a chip. In this dissertation, we systematically investigated a simple, scalable, low-cost and lithography-free strategy to fabricate three-layered broadband super absorbing metasurface structures, and application development based on this strategy. In Chapter 2, we employ metal-dielectric nanocomposite metamaterials to develop large area inexpensive thin-film resonant and nonresonant on-chip absorbers. The limitations for narrow band and expensive fabrication cost for previously reported plasmonic/metamaterial structures are largely overcome. In Chapter 3, an ultra-broadband super absorbing metasurface is reported to work as a universal substrate for low cost and high performance surface enhanced Raman spectroscopy (SERS) sensing of chemicals and drugs. In Chapter 4, by manipulating the morphology and composite of the top random nanoantenna layer, the broadband super absorbing metasurface substrate is demonstrated for strong field localization and enhanced surface enhance nonlinear optical processes. This dissertation aims to analyze both the strength and the limit of this strategy and paves the way towards miniaturization of sensing devices."]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["Super Absorbing Metasurfaces: From Fundamental Investigation and Nanomanufacturing to Applications"]}]}],"canonical_facts":{"dc:contributor":["Gan, Qiaoqiang","Electrical Engineering"],"dc:creator":["Zhang, Nan; 0000-0002-1517-333X"],"dc:date":["2019-04-04T20:32:31Z","2019","2019-01-16 02:23:33"],"dc:description":["Ph.D.","The original idea of a blackbody was introduced by Gustav Kirchhoff in 1860, which is an idealized object that absorbs all radiation incident upon it.
