Calculating Transmission of Electromagnetic Wave in COMSOL

[Yacobito]

Hello All,

I have a fundamental Comsol question that maybe you can help me with.

If I am in say a 2-D In-Plane TE Mode. I am inputting a wave that will propagate left to right. What is the best way solve for the resulting field that is transmitted to the right boundary, regardless of what medium or pillars I put in its path. Seems like a simple to task to compute the transmission, but I am struggling.

I am assuming I will need to set up a time step to integrate over to make sense of it. Can this be done in the "Harmonic Propagation" mode or does it need to be in "Transient Propagation". Any input is welcome.

Thanks,
Jacob

Hello Jacob,

Thank you for your question. To calculate the transmission of the electromagnetic wave in your system, you can use the "Transmission Line" feature in COMSOL. This allows you to specify the input wave and the material properties of your system, and then calculates the transmitted wave at the output boundary. You can also use the "Time Domain" solver in COMSOL to take into account the time evolution of the wave as it propagates through your system. Both the "Harmonic Propagation" and "Transient Propagation" modes can be used, depending on the specific parameters and properties of your system. It may be helpful to consult the COMSOL documentation or reach out to their support team for further assistance with setting up your simulation. I hope this helps. Good luck with your research!

Best,
