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.

0084423 Maradudin这个为期三年的奖项，支持美国-西班牙合作研究表面缺陷对表面等离子体激元的散射，涉及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。他们的研究的目标是产生方程描述的散射表面等离子体激元（SPP）的表面缺陷，可以在一个有效的方式数值求解;提供有关如何散射取决于缺陷的功能信息;并产生明确的解析表达式非常窄的缺陷，以及在光子扫描隧道显微镜实验中感兴趣的缺陷配置。联合S.研究人员带来了这种合作访问一流的计算资源和非理想表面电动力学的专业知识。这是补充西班牙调查员的计算技能和他的经验，在处理电动力学的扰动表面。本文的研究结果对无序介质的电磁学研究具有一定的参考价值。
