[start here]Hi all, I've provided a link to a previous discussion that somewhat addresses my question, but I am still looking for additional insight. Essentially, I am looking to simulate a axisymmetric structure. I'd like to investigate the optical properties of the structure after introducing a plane-wave excitation source. From the linked description, it appears that it is relatively difficult to achieve this in Comsol because of the underlying assumption that the axisymmetry exists through the entire module. I've looked into some other sources which discuss the breakdown of a traditional plane-wave into Jacobi-Anger expansion of modes, but I do not know if this is the correct approach. I'm curious, is it best to simulate the 3D model instead due to the plane-wave excitation difficulties? Or is there a simple work around. Thank you!
