Hello everyone.<\/p>\n

I am studying the EME solver in MODE to use the EME solver for simulations.<\/p>\n

I am trying to obtain the following graph using the mode convergence sweep tool as described<\/p>\n

in ‘Convergence testing process for EME simulations’ and ‘Convergence testing method’: <\/p>\n

(https:\/\/optics.ansys.com\/hc\/en-us\/articles\/360037172994-Convergence-testing-process-for-EME-simulations)<\/p>\n

<\/p>\n

In the course of my study using relevant examples, I learned that to obtain S_52, three modes need to be selected for each port.<\/p>\n

However, despite referring to the mode convergence sweep(https:\/\/www.youtube.com\/embed\/cTM5ICNg_50), I could not obtain the S-parameter and mode profile as shown in the attached image.<\/p>\n

<\/p>\n

To summarize, I’m curious about how to select modes at each port to obtain the S_52 graph based on the number of modes for convergence testing.<\/p>\n

I attempted to proceed with the fundamental mode but did not achieve the desired results. Additionally, when executing the ‘testing_convergence_EME.lsf’ script, an error occurred at line 63 with ‘S52 = S.s52;’<\/p>\n

Apart from simulation questions, I also have conceptual inquiries. I find it difficult to understand the meaning of ‘S_52’, which is described as ‘the conversion efficiency from the TE1 input mode to the TM0 output mode.’ Additionally, I’m curious about the reason for confirming mode 2 from port 1 input to port 2 output, as seen in the ‘S-matrix index mapping’ image.<\/p>\n

I still feel like I’m in the early stages of learning and would appreciate any advice. Please let me know if there are any aspects I’m missing.<\/p>\n

Thank you.<\/p>\n

If you have any other questions or need further clarification, feel free to ask.<\/p>\n","protected":false},"template":"","class_list":["post-349601","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
