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.

0084423Maradudin 这个为期三年的奖项支持美国-西班牙关于表面缺陷引起的表面等离子体激元散射的合作研究，涉及加州大学欧文分校的 Alexei Maradudin 和马德里材料结构研究所的 Jose Sanchez-Gil，西班牙。他们研究的目标是建立描述表面等离激元（SPP）因表面缺陷而散射的方程，并且可以有效地进行数值求解；提供有关散射如何取决于缺陷特征的信息；并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配置产生明确的分析表达式。美国研究人员为此次合作带来了非理想表面电动力学方面的一流计算资源和专业知识。西班牙研究人员的计算技能和处理扰动表面电动力学的经验补充了这一点。这项研究的结果将有利于无序介质的电磁学研究。
