Photoabsorption analysis of metal nanoparticles by hybrid quantum/classical scheme

引用

Optoelectronics Letters 2022年第9期18卷 519-524页

作者： bashir Fotouhi Faculty of Electrical and Computer Engineering University of KurdistanKurdistanIran

The hybrid quantum/classical scheme(HQCS) is used for the photoabsorption analysis of metal nanoparticles. The HQCS divides the structure of interest into quantum and classical subsystems. First, we calculate and report Lorentz parameters for gold(Au), silver(Ag), aluminum(Al), chromium(Cr), and nickel(Ni) permittivities used in the classical subsystem. Then, photoabsorption spectra were obtained from HQCS for the single nanoparticle structures with and without two sodium(Na) atoms. The Au, Ag, Al, Cr, and Ni show strong sensitivity to the presence of the atomic subsystem. This work could pave the way for how coupled plasmon modes between metal nanoparticles and atomic structures can be utilized for sensing devices.

Improved Geological Mapping Using Landsat-5 TM Data in Weixi Area, Yunnan Province, China

引用

Geo-Spatial Information Science 2005年第2期8卷 110-114页

作者： Tarik bashir Benomar State Key Laboratory of Information Engineering in Surveying Mapping and Remote Sensing Wuhan University 129 Luoyu Road Wuhan 430079 ChinaPh.D candidate

Different image processing algorithms have been evaluated in the context of geological mapping using Landsat TM data. False color composites, the principal component imagery, and IHS decorrelation stretching method for Landsat-5 TM data have been found useful for delineating the regional geological features, mainly to provide the maximum geological information of the studied area . The study testifies that using which image processing yields best results for geological mapping in arid and semiarid regions by preserving morphological and spectral information. Generally, the studied area can be divided into three main geological units: Basaltic intrusive rocks, Metamorphic with varying intensities and Sedimentary rocks.
