利用计算资源进行现代物理教育已变得越来越普遍，特别是在COVID-19大流行的催化下，远程学习被广泛实施。在此，我们报告了一个开源软件，供学生和教师按需模拟一维光子晶体（1D-PC）的光学反射行为，一维光子晶体是一种用于理解与材料科学和光学物理相关的光-物质相互作用的模型系统。具体来说，我们的MATLAB应用程序，反射，采用了一个适应性的传输矩阵法模拟，可以考虑几个关键的材料设计参数的影响，包括界面粗糙度和层的几何形状，以确定用户定义的1D-PC的反射光谱。通过将我们的代码打包到图形用户界面中，该软件易于使用，并且绕过了用户对任何编码经验的要求，可以广泛用作高中/本科课堂和K-12推广活动的教育工具。我们相信，ReflectSim提供了巨大的潜力，通过使更多的参与学习经验，帮助学生理解纳米结构层状材料和相关的科学概念的光学现象。
Leveraging computational resources for modern physics education has become increasingly prevalent, especially catalyzed by the COVID-19 pandemic when distance learning is widely implemented. Herein, we report an open-source software for students and instructors to on-demand simulate optical reflection behaviors of one-dimensional photonic crystals (1D-PCs), a model system for understanding light–matter interactions relevant to materials science and optical physics. Specifically, our MATLAB application, ReflectSim, employs an adapted transfer matrix method simulation and can account for the effects of several critical material design parameters, including interfacial roughness and layer geometry, to determine the reflectance spectrum of user-defined 1D-PCs. By packing our codes into a graphical user interface, this software is simple to use and bypass the requirement of any coding experiences from users, which can be widely used as an education tool in high school/undergraduate classrooms and K-12 outreach activities. We believe that ReflectSim provides great potential for assisting students in understanding optical phenomenon in nanostructured layered materials and relevant scientific concepts through enabling more engaging learning experiences.
