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

[0084423 . 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极化的散射，参与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等离子激元（SPP）由表面缺陷散射的方程，这些方程可以有效地用数值方法求解；提供散射如何依赖于缺陷特征的信息；并对非常窄的缺陷和光子扫描隧道显微实验中感兴趣的缺陷构型给出明确的解析表达式。这位美国研究者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。这是由西班牙研究者的计算技能和他的经验，在处理电动力学的扰动表面补充。这一研究结果对一般无序介质的电磁学研究具有重要意义。

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.
