COMSOL Wave Optics 4.4 Help
How would you model the transmittance of light through multiple layers of material?

We only have access to the wave optics module and the structural mechanics. I have heard that the RF module and wave optics module are similar. Would you know how to get started with this at all?

Sorry, I'm not familiar with Wave Optics module, which is newly introduced only in 4.4. You can check what equations it is solving. -- Pu, ZHANG DTU Fotonik

In principle it will be straightforward in RF module. Of course if it is doable depends on how large your system is. -- Pu, ZHANG DTU Fotonik

It turns out that I do have the RF module for COMSOL. What you be able to explain how to set up the parameters, variables, and boundary conditions that is needed to find transmission vs. wavelength?...

You really need to read the documentation. Although I complained many times the documentation is quite bad, your problem definitely can be solved by reading documentation. -- Pu, ZHANG DTU Fotonik

Ryan, There is example from the Comsol model library for analysis of reflectance and transmittance of light through the layered material:www.comsol.com/model/fresnel-equations-14713 Note that both RF...

Hey Sergei, thanks for the reply. I've gone through the tutorial and the documentation on what they used. I feel like I understand how they got their results. I have a few questions that you hopefully...

Ryan, 1. You still need two ports for transmission through multiple interfaces (you can even get away with one port for incident wave and replace exit port with PML). 2. Probably, you mean wave-vectors...

Thanks Sergei, your answers are very helpful. Another question I had is that currently the Fresnel model has the has the wave vectors coming in from the side of the material. To study and model EM...

Ryan, The incident wave is coming in from the top surface. You can see this by plotting Poynting vector which gives the direction of the power flow and, hence, the direction of the wave propagation, as...

Dear all, The Fresnel example works well to understand the use of S parameters to calculate the transmitted and reflected power. A 2D model is not so difficult to derived from it. In a 2D example the...
