| 2 | Multifunctional interleaved geometric-phase dielectric metasurfaces显示文摘Shared-aperture technology for multifunctional planar systems,performing several simultaneous tasks,was first introduced in the field of radar antennas.In photonics,effective control of the electromagnetic response can be achieved by a geometric-phase mechanism implemented within a metasurface,enabling spin-controlled phase modulation.The synthesis of the shared-aperture and geometric-phase concepts facilitates the generation of multifunctional metasurfaces.Here shared-aperture geometric-phase metasurfaces were realized via the interleaving of sparse antenna sub-arrays,forming Si-based devices consisting of multiplexed geometric-phase profiles.We study the performance limitations of interleaved nanoantenna arrays by means of a Wigner phasespace distribution to establish the ultimate information capacity of a metasurface-based photonic system.Within these limitations,we present multifunctional spin-dependent dielectric metasurfaces,and demonstrate multiple-beam technology for optical rotation sensing.We also demonstrate the possibility of achieving complete real-time control and measurement of the fundamental,intrinsic properties of light,including frequency,polarization and orbital angular momentum. | Elhanan Maguid Igor Yulevich Michael Yannai Vladimir Kleiner Mark L Brongersma Erez Hasman | 2017 | Light(Science & Applications)2017，6，1： | 7 |

| 4 | 贸易、FDI和企业的组织形式显示文摘国际贸易和外国直接投资(FDI)一直以来都身居全球增长最快的经济活动之列。2003年,全球货物出口额直逼73,000亿美元,全球商业服务出口额将近18,000亿美元;同时,全球FDI流入额也接近5,600亿美元。然而,在1990年到2001年跨国公司海外分支机构营业收入的扩张速度甚至要比全球货物出口和非要素服务出口的迅猛增长快得多。 | Elhanan Helpman 陈华姝 郑凡奇 张定忠 | 2006 | 经济资料译丛2006，，4： | 4 |
