Linear and Nonlinear Optical Phenomena at Metal Surfaces (U.S.-Egypt Cooperative Science; Science in Developing Countries)

技术描述：这个由宾夕法尼亚大学和艾因沙姆斯大学参与的美埃合作研究项目涉及电磁现象的一般领域在金属表面。项目资金将允许艾因沙姆斯大学的团队在宾夕法尼亚大学埃利亚斯·伯斯坦博士的实验室工作不同时期。这项合作研究将从实验和理论上研究表面电子激发对贵金属表面线性和非线性光学响应的贡献。预计研究结果将确定所涉及的表面激发的具体性质。这个材料研究项目通过使美国和埃及的顶尖专家能够将互补的人才结合在一起，并在彼此感兴趣和有能力的领域汇集研究资源，实现了促进科学知识的计划目标。

Technical Narrative: This U.S.-Egypt collaborative research project involving the University of Pennsylvania and Ain Shams University is in the general area of electromagnetic phenomena at metal surfaces. Project funding will allow the team from Ain Shams University to work for various periods of time in the laboratory of Dr. Elias Burstein at the University of Pennsylvania. The collaborative research will investigate experimentally and theoretically the contributions from surface electronic excitations to the linear and nonlinear optical response of noble metal surfaces. Research results are expected to ascertain the specific nature of the surface excitations involved. This project in materials research fulfills the program objective of advancing scientific knowledge by enabling leading experts in the United States and Egypt to combine complementary talents and pool research resources in areas of strong mutual interest and competence.
