Statistics of Electromagnetic Propagation and Localization

该个人研究者奖将支持一个项目，其目的是使用微波和光学测量来研究电磁输运从扩散传播到局部化转变过程中静态和动态方面的变化特征。通过使用各种各样的样本、测量技术和方法，预计将开发出一种波传播的描述，可以有效地处理安德森局域化转换的复杂性，这是无序系统中波输运的试金石。将采用一种新的统计方法，研究单个样本而不是整体或随机样本的运输统计。统计方法的发展将进一步加深我们对一系列基础和应用问题的理解，包括：电子介观物理、随机介质中的激光、光子带隙材料中的传播、液晶和结构薄膜、多天线蜂窝通信、医学成像、大气通信和传感。这项工作的成功将加强新生的纽约市立大学光子中心，该中心的建立是为了加强纽约市大都市区的技术基础，并吸引来自我们附近地区和世界各地的学生和研究人员。参与这项研究的研究生和本科生将获得世界一流的技能和思想培训，这些技能和思想将对他们未来的学术或技术事业有用。该个人研究者奖将支持一个项目，其目标是使用微波和光学测量来绘制电磁传输从扩散传播到强辐射捕获转变过程中静态和动态方面的变化特征。通过使用各种各样的样本、测量技术和方法，预期将开发出一种波传播的描述，可以有效地处理随机介质中波传输的复杂性。这项研究将进一步加深我们对电子传导、无序介质中的激光、光子材料、液晶和人造薄膜中的波传播等基本问题的理解。此外，该研究还将对蜂窝通信、医学成像、大气通信和传感等应用问题产生影响。这项工作的成功将加强新生的纽约市立大学光子中心，该中心的建立是为了加强纽约市大都市区的技术基础，并吸引来自我们附近地区和世界各地的学生和研究人员。参与这项研究的研究生和本科生将接受世界级的技能和思想培训，这些技能和思想将对学术或技术事业有用。

This individual investigator award will support a project with the objective of using microwave and optical measurements to study the changing character of both static and dynamic aspects of electromagnetic transport in the transition from diffusive propagation to localization. By using a wide variety of samples, measurement techniques, and methodologies, it is expected that a description of wave propagation will be developed that can deal effectively with the complexity of the Anderson localization transition, which is the touchstone of wave transport in disordered systems. A new statistical approach will be pursued, in which the statistics of transport in a single sample, rather than in an ensemble or random samples, will be studied. The statistical approaches that will be developed are expected to further our understanding of a full range of fundamental and applied problems including: electronic mesoscopic physics, lasing in random media, propagation in photonic band gap materials, liquid crystals, and structured thin films, multiantenna cellular communication, medical imaging, atmospheric communication and sensing. The success of this work will strengthen the nascent CUNY Photonic Center, established to strengthen the technological base of the New York City metropolitan area and to serve as a magnet for students and researchers from our immediate area and around the world. The graduate and undergraduate students involved in this research will receive world-class training in skills and ideas that will be of use to their future academic or technological careers.This individual investigator award will support a project with the objective of using microwave and optical measurements to chart the changing character of static and dynamic aspects of electromagnetic transport in the transition from diffusive propagation to strong trapping of radiation. By using a wide variety of samples, measurement techniques, and methodologies, it is expected that a description of wave propagation will be developed that can deal effectively with the complexity of wave transport in random media. The research will further our understanding of such fundamental issues as electronic conduction, lasing in disordered media, and wave propagation in photonic materials, liquid crystals, and fabricated thin films. In addition, the research will have an impact on applied problems including bandwidth enhancement for cellular communication, medical imaging, and atmospheric communication and sensing.
