A plasmonic photopatterning technique is proposed and demonstrated for aligning the molecular orientation in liquid crystals (LCs) in patterns with designer complexity. Using plasmonic metamasks in which target molecular directors are encoded, LC alignments of arbitrary planar patterns can be achieved in a repeatable and scalable fashion withunprecedentedly(More)
Although high-resolution remote sensing (RS) images can supplement the reference map's deficiency in LADAR (Laser Radar) referenced navigation system over plain area, their different imaging modes still leave great errors' introduction into the positioning process. As positioning is commonly accomplished by matching the edges extracted as the obvious(More)
Aligning liquid crystal (LC) molecules into spatially non-uniform orientation patterns is central to the functionalities of many emerging LC devices. Recently, we developed a new projection photopatterning technique by using plasmonic metamasks (PMMs), and demonstrated high-resolution and high-throughput patterning of molecular orientations into arbitrary(More)
Irrigated land is the main region which produces a large amount of foodstuff. It has great meaning in the aspect of agriculture, foodstuff security and regional water resource development. Until now it has seldom researched on irrigated land by using remote sensing. This paper retrieves soil water by using crop water stress index (CWSI) during crop growth.(More)
In this paper, a new function model for determining the minimum and maximum detectable deformation gradient in synthetic aperture radar interferometry (InSAR) with Envisat ASAR images is developed. The model incorporates the parameters of both interferometric coherence and multilook operator for 1, 5 and 20, rather than the interferometric coherence only in(More)
On page 2353, Q.-H. Wei and co-workers present a plasmonic photopatterning technique for aligning liquid-crystal (LC) molecules into arbitrarily complex patterns. By encoding target molecular orientations in plasmonic metamasks, this technique enables repeatable and scalable alignments of LCs with high spatial resolution and high throughput, which promises(More)
