This research will study electrodynamics near surfaces with the goal of further fundamental understanding and contact with experiments. The primary effort will be on the linear response of surfaces to an applied field by making use of the d- parameter formalism. A wider range of frequencies will be studied, and various paths away from jellium models will be developed so that effects of discrete atomic structure can be incorporated into the model. The resulting theory will be applied to systems ranging from simple metals to multiple quantum wells. A parallel effort will be made to transfer the model developed to nonlinear response properties such as second harmonic generation at surfaces of cubic materials.

这项研究将研究表面附近的电动力学，目的是进一步了解基础并与实验接触。主要的工作将是通过利用d参数形式来研究表面对外加磁场的线性响应。将研究更广泛的频率范围，并将开发各种远离凝胶模型的路径，以便将离散原子结构的影响纳入模型中。由此产生的理论将应用于从简单金属到多量子井的各种系统。同时，还将努力将发展的模型转化为非线性响应特性，如立方体材料表面的二次谐波产生。
