This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The work I intend to do is a part of a simulation project where I simulate the full maxwell equations to find the near field of 20nm diameter polystyrene beads which has dye molecules in it. To keep the simulation close to the real situation I need to know the complex refractive index of the beads with the dye. The procedure is as follows,First measure the extinction coefficient with the Perkin Elmer UV-Vis absorption spectrometer. Then with the known values of concentration and particle size its possible to relate the measurement to the complex refractive index.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目和 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 我打算做的工作是模拟项目的一部分，在该项目中，我模拟完整的麦克斯韦方程，以找到其中含有染料分子的 20nm 直径聚苯乙烯珠的近场。 使模拟接近真实情况 我需要知道复折射率 带有染料的珠子。 程序如下，首先测量 使用 Perkin Elmer UV-Vis 吸收光谱仪测量消光系数。然后与已知的 浓度和颗粒尺寸的可能值 将测量结果与复折射率联系起来。
