1电环形谐振腔表面几何参数对太赫兹超材料吸收体性能的影响(英文)显示文摘本文分析了电环形谐振腔的几何参数对超材料吸收体吸收率的影响。文中详细分析了电环形谐振腔参数、介电层(间隔物)厚度和电环形谐振腔厚度对超材料吸收体的影响,在此基础上,设置正交实验分析了几种参数的综合影响,最终获得超材料的理论吸收率。根据上述结果,制备了2个超材料吸收体的原理样机,经实验测得,原理样机的窄带吸收率高于98%。本文的研究成果为高性能吸收器的设计提供了指导。GOMON Daniel SEDYKH Egor RODRíGUEZ Sebastian IDELFONSO Tafur Monroy ZAITSEV Kirill VOZIANOVA Anna KHODZITSKY Mikhail 2018中国光学2018,11,1:3
2High-speed ultra-wideband wireless signals over fiber systems:photonic generation and DSP detection显示文摘We firstly review the efforts in the literature on ultra-wideband (UWB)-over-fiber systems. Secondly,we present experimental results on photonic generation of high-speed UWB signals by both direct modulation and external optical injecting an uncooled semiconductor laser. Furthermore,we introduce the use of digital signal processing (DSP) technology to receive the generated UWB signal at 781.25 Mbit/s. Error-free transmission is achieved.Timothy Braidwood Gibbon Idelfonso Tafur Monroy 2009The Journal of China Universities of Posts and Telecommunications2009,16,4:2
350 GHz optical true time delay beamforming in hybrid optical/mm-wave access networks with multi-core optical fiber distribution显示文摘We propose and experimentally validate an optical true time delay beamforming scheme with straightforward integration into hybrid optical/millimeter(mm)-wave access networks. In the proposed approach, the most complex functions, including the beamforming network, are implemented in a central office, reducing the complexity and cost of remote antenna units. Different cores in a multi-core fiber are used to distribute the modulated signals to high-speed photodetectors acting as heterodyne mixers. The mm-wave carrier frequency is fixed to 50 GHz(VBand), thereby imposing a progressive delay between antenna elements of a few picoseconds. That true time delay is achieved with an accuracy lower than 1 ps and low phase noise.álvaro Morales Idelfonso Tafur Monroy Fredrik Nordwall Tommi Sφrensen 2018Chinese Optics Letters2018,16,4:2

14On the calibration of rotational augmentation models for wind turbine load estimation by means of CFD simulations显示文摘In this work the improved version of an engineering model which accounts for rotational augmentation effects by means of computational fluid dynamics(CFD)calibration is explored and discussed.Based on an analysis of the NREL Phase VI wind turbine,the novel modeling is presented,which uses as base line the formulation proposed by Chaviaropoulos and Hansen.The model is calibrated based on CFD simulations using OpenFOAM.The corresponding correction of the two dimensional polars is straightforward implemented within MoWiT,an in-house software for load calculation.The novel formulation results in improved lift and drag coefficients prediction in all considered cases,reducing the deviation with respect to the rotating CFD cases down to few percent.The optimal configuration including the correction for tip effects of Shen shows better agreements at the very tip of the blade.Furthermore the range of applicability for large wind turbine rotor blades based on a virtual 10MW rotor model is discussed.Belen Soledad Burgos Tafur Elia Daniele Bernhard Stoevesandt Philipp Thomas 2020Acta Mechanica Sinica2020,36,2:1
