Wave Optics, Working with Wavelengths We should all be familiar with this equation: speed of light = wavelength * frequency. Engineers and researchers working within wave optics concern themselves with thewavelengthaspect of the equation; they treat light as a wave. Many optical devices are much l...
comsol中的RF..Maxwell方程组没有什么区别,边界等小细节上有些不同,但是应该不影响使用,比较重要的不同是RF针对射频有个传输线方程,波动光学针对波长同传播尺寸相差较大的问题添加了束包络法。具体可以参考帮助文档中
is “slowly varying”, so we don’t need to resolve the wavelength. Instead, we only need to resolve the slow wave of the envelope. Because of this process, simulating large-scale wave optics problems is possible on personal computers. ...

COMSOL Multiphysics Tutorials First, there are the Tutorial videos, which come in a couple of different forms. These videos will all have step-by-step instructions that you can follow along with and reproduce, but the videos differ in the content being shown. Model Tutorials teach you how to...
本次18 分钟入门将带您学习模拟仿真波动光学的基本要点。波动光学仿真带来了设计和优化光学系统的新机遇。应用示例包括定向耦合器、非线性光波导、大型光学系统、超材料等等。COMSOL Multiphysics® 软件提供了模拟此类系统和创建定制仿真 App 的能力。在本次网络研讨会中,我们将演示硅脊形波导的模拟。
以上就是文章提出的结构,文中定义了δw=Δw/(w1+w2)以及δs的非对称参数。其中,Δw=w1−w2。用商用软件COMSOL计算了本文的一些结果。用 COMSOL中Wave Optics模块中的Electromagnetic Waves, Frequency Domain求解器,频域中的本征频率eigenfrequency计算了文中的模式Q值。
The Multiscale 3D Packed Bed Reactor tutorial has been upgraded to include a plate with holes located at the inlet and realistic second-order reversible kinetics. It also considers the transient behavior of the reactor at start-up. When modeling concentrated gas mixtures with theReaction Engineering...
