U.S.-Spain Cooperative Research: Scattering of Surface-Plasmon Polaritons by Surface Defects: Applications to Photon-Scanning Optical Microscopy'

Maradudin这个为期三年的奖项支持美国和西班牙合作研究表面缺陷对表面等离子激元的散射，获奖者包括加州大学欧文分校的Alexei Maradudin和西班牙马德里材料结构研究所的Jose Sanchez-Gil。他们的研究目标是建立描述表面缺陷对表面等离子体激元(SPP)的散射的方程，该方程可以以有效的方式进行数值求解；提供有关散射如何依赖于缺陷特征的信息；以及为非常窄的缺陷以及光子扫描隧道显微镜实验中感兴趣的缺陷构型提供显式的解析表达式。这位美国研究人员为这次合作带来了一流的计算资源和非理想表面电动力学方面的专业知识。西班牙研究人员的计算技能和他在处理扰动表面的电动力学方面的经验补充了这一点。这一研究结果将对无序介质的电磁学研究有一定的参考价值。

0084423MaradudinThis three-year award, which supports U.S.-Spain cooperative research on scattering of surface-plasmon polaritons by surface defects, involves Alexei Maradudin of the University of California at Irvine and Jose Sanchez-Gil at the Institute of the Structure of Materials in Madrid, Spain. The objectives of their research are to produce equations describing the scattering of surface plasmon polaritons (SPP) by surface defects that can be solved numerically in an efficient manner; to provide information about how the scattering depends on the features of the defects; and to yield explicit analytical expressions for very narrow defects as well as for defect configurations of interest in photon scanning tunneling microscopy experiments. The U. S. investigator brings to this collaboration access to first rate computational resources and expertise in electrodynamics of nonideal surfaces. This is complemented by the Spanish investigator's computational skills and his experience in dealing with the electrodynamics of perturbed surfaces. The results of this research will benefit the electromagnetics of disordered media in general.
