Item type:Item, Plasmonic thermal emitter using perfect absorber made of metallic disk on SiO2(2012) ;Abbas, Mohammed Nadhim ;Cheng, Cheng-Wen ;Chang, Yia-Chung ;Shih, Min-HsiungChen, Hung-HsinIt is shown that the metallic disk structure can be used as an efficient narrow-band thermal emitter in the IR region. The absorption spectra of such structure are investigated both theoretically and experimentally. Calculations of thermal radiation properties of the metallic disk show that the metallic disk is a perfect emitter at a specific wavelength. The metallic disk exhibits only one significant localized surface plasmon polariton mode for both TM and TE polarizations simultaneously.Item type:Item, Wide-angle polarization independent infrared broadband absorbers based on metallic multi-sized disk arrays(2012-04-23) ;Cheng, Cheng-Wen ;Abbas, Mohammed Nadhim ;Chiu, Chao-Wei ;Lai, Kun-TingShih, Min-HsiungTwo-dimensional metallic broadband absorbers on a SiO2/Ag/Si substrate were experimentally studied. The absorptivity of such structure can be increased by tailoring the ratio of disk size to the unit cell area. The metallic disk exhibits a localized surface plasmon polariton (LSPP) mode for both TE and TM polarizations. A broadband thermal emitter can be realized because the LSPP mode is independent of the periodicities. By manipulating the ratios and disk sizes, a high-performance, wide-angle, polarization-independent dual band absorber was experimentally achieved. The results demonstrated a substantial flexibility in absorber designs for applications in thermal photovoltaics, sensors, and camouflage. (C) 2012 Optical Society of America
