WebbAbstract: An innovative deterministic approach to the optimal power synthesis of mask-constrained shaped beams through the concentric-ring isophoric sparse arrays is presented. The design procedure exploits at best the state-of-the-art techniques, respectively, available in the cases of circular-ring isophoric arrays radiating pencil … Webbshaped [ ʃeipt ] adj. shaped to fit by or as if by altering the contours of a pliable mass (as by work or effort) "a shaped handgrip" 同义词:moldedwrought. having the shape of "a …

WebbIn high-resolution optical coherence tomography (OCT) imaging, beam shaping for increasing the depth of focus is desirable because it allows to capture a full axial depth scan at constant resolution, with no need for shifting the focus. Bessel beams generated with axicons have been the most widely studied approach [1], but other shaped beams … Webb27 juni 2006 · 2009-09-09 求助海运船务的一些问题! 12 2011-04-10 关于船舶资料的缩写 41 2013-12-28 船舶方面一般常识 14 2024-06-17 船舶国籍证书上面的长度是loa还是lpp … orb of nergal

WebbShaped beam: A = E(x,y,z) How to describe a shaped beam? 1. The fields expressions must satisfy the Maxwell equations. 2. The theoretical fields describe as precisely as possible the real... Webb8 maj 2024 · The Gaussian beam is shaped into a rectangular flat-top beam with a size of 15 × 60 mm using the aspherical cylindrical lenses. The working distance is 500 mm, and the glass material is ZnSe. 3.1. Design of Aspherical Cylindrical Lenses WebbIts gain and beam shape is decided by the turn numbers of the helixes. It is easier to get shaped beam with more helix turns, whereas the reliability of the structure need be considered with more turns. The turn number of each helix is chosen as 4 in this case. The antenna is omni-directional in the azimuth plane and is shaped with conical orb of night meaning
