Integrating conventional optics into compact nanostructured surfaces is the goal of flat *** the enormous progress in this technology,there are still critical challenges for real-world applications due to the limited operational efficiency in the visible region,on average lower than 60%,which originates from absorption losses in wavelengththick(~500 nm)*** issue is the realization of on-demand optical components for controlling vectorial light at visible frequencies simultaneously in both reflection and transmission and with a predetermined wavefront *** this work,we developed an inverse design approach that allows the realization of highly efficient(up to 99%)ultrathin(down to 50 nm thick)optics for vectorial light control with broadband input-output responses in the visible and near-IR regions with a desired wavefront *** approach leverages suitably engineered semiconductor nanostructures,which behave as a neural network that can approximate a user-defined input-output *** performance results from the ultrathin nature of these surfaces,which reduces absorption losses to nearnegligible ***,we discuss polarizing beam splitters,comparing their performance with the best results obtained from both direct and inverse design techniques,and new flat-optics components represented by dichroic mirrors and the basic unit of a flat-optics display that creates full colours by using only two subpixels,overcoming the limitations of conventional LCD/OLED technologies that require three subpixels for each composite *** devices can be manufactured with a complementary metal-oxide-semiconductor(CMOS)-compatible process,making them scalable for mass production at low cost.

本文从测量射线参数出发进行反向射线追踪,导出倾角时差校正(DMO)的公式。经过DMO后,可以从一组等炮检距剖面得出共分角线点道集。用于对这些道集进行叠加的速度值与界面倾角无关。对经过DMO的资料的等时切片进行叠前成象(PSI),就可以把分布在圆上的绕射能量沿圆弧加起来,并放在圆弧上对应于最大炮检距的位置。经过这两种处理,再应用标准的速度分析和叠加方法,就可得出偏移后的剖面。这两种处理均与速度无关。最后用物理模型试验说明了DMO和PSI的效果是好的。

Darcy-forchheimer flow by rotating disk with partial slip

Applied Mathematics and Mechanics(English Edition) 2020年第5期41卷 741-752页

The viscous dissipation and heat transfer in the Darcy-forchheimer flow by a rotating disk are examined. The partial slip conditions are invoked. The optimal series solutions are computed via the optimal homotopic analysis method(OHAM). The thermophoresis and Brownian motions are studied. The Darcy-forchheimer relation characterizes the porous space. The roles of influential variables on the physical quantities are graphically examined. A reduction in the local Nusselt number is observed through thermophoresis and thermal slip parameters. The local Sherwood number depicts an increasing trend for the higher Brownian motion and concentration slip parameters.

Advances in Pure Mathematics 2013年第1期3卷 34-40页

作者： Hariwan z. Ibrahim Department of Mathematics Faculty of Science University of Zakho Zakho Iraq

In this paper, we introduce a new class of b-open sets called Bc-open, this class of sets lies strictly between the classes of θ-semi open and b-open sets. We also study its fundamental properties and compare it with some other types of sets and we investigate further topological properties of sets and we introduce and investigate new class of space named Bc-compact.

THE STUDY Of AIRPORTTERRAIN EffECTS ON AUTOLAND fOR ANY AIRPLANE

引用

航空学报 1993年第12期 596-602页

作者： Sai f. Lee No 804 Perry Arc. Montebello Ca 90640 Dr

The terrain profile at several airports has caused some difficulty with autolands on the DC-10 and MD-80. Some operators have reported that the pilot had to disconnect the flight guidance system during flare and land manually. At present, the autoland guidance system is not uniquely designed to handle the variations of terrain. Since there is no accurate substitute for radio altitude(h) the only variable left to improve is radio altitude rate (h).

gn:justify;"> Granulosa cell tumors belong to the group of stromal and sex cord tumors of the ovary. The adult type is the most common type and usually occurs during the perimenopausal period while the juvenile type mostly affects young women. This is a report of a 26 years old woman who presented an adult type of granulosa cells tumor, with review of the literature. She complained abdominal pain and distension associated with abundant ascites and underwent a right adnexectomy. The pathology examination diagnosed an adult granulosa cell tumor. The two entities of granulosa cell tumors (juvenile and adult types) are distinguished by their characteristic morphological aspects on histological examination allowing diagnostic orientation.
