Apparatus and method for providing a selectively absorbing structure
TL;DR: In this article, an apparatus that selectively absorbs electromagnetic radiation is described, which includes a conducting surface, a dielectric layer formed on the conducting surface and a plurality of conducting particles distributed on the dielectrics layer.

Wind-induced structural response of a large telescope
TL;DR: In this article, the authors investigated the dynamic behavior of the Gemini South 8m======telescope structure in terms of wind pressure and structural response. But the authors focused on the wind velocity and pressure measurements and not on the structural response of the telescope.
Proceedings ArticleDOI
Cross-coax fed wideband solar patch antenna
TL;DR: In this paper, a cross-coax fed low-profile short-circuited suspended patch antenna combined with a polycrystalline silicon (poly-Si) solar cell operating as a radiating patch element is proposed for self-powered 2.4 GHz band WLAN and 2.3/2.5 GHz band WiMAX networks.

Design, construction and performance of a small, low cost anechoic measuring system for research applications
D. Green,David R. Smith +1 more
TL;DR: A low cost anechoic measuring system, designed specifically for measurements of high performance feed horns within the range 18-30 GHz, and a simple antenna positioner, which interfaces with a network analyser to achieve a fully automated magnitude and phase pattern measuring system.

Dual-band metamaterial absorber with a low-coherence composite cross structure in mid-wave and long-wave infrared bands
Enzhu Hou,Zheng Qin,Zhongzhu Liang,Meng Dejia,Xiaoyan Shi,Fuming Yang,Wenjun Liu,Hua Liu,Haiyang Xu,David R. Smith,Yichun Liu +10 more
TL;DR: A dual-band absorber based on the composite cross structure (CCS) in both MWIR and LWIR bands was proposed, with absorption peaks of 4.28 μm and 8.23 μm showing that absorption increases as the incident angle increases, and can be a good candidate for applications in thermal emission, detection and solar energy harvesting.
