Calculating Transmission of Electromagnetic Wave in COMSOL

Click For Summary
SUMMARY

This discussion focuses on calculating the transmission of electromagnetic waves in COMSOL, specifically in a 2-D In-Plane TE Mode. The user, Jacob, seeks guidance on determining the transmitted field at the right boundary when a wave propagates left to right, regardless of the medium or obstacles present. Key considerations include whether to utilize the "Harmonic Propagation" mode or the "Transient Propagation" mode for accurate results. The conversation highlights the importance of setting up appropriate time steps for integration in the simulation process.

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
