how can I learn to design a waveguide to generate spr with a layer 0f gold and then replace it with several metals by mode in an easy way?
I apologize because my English is not strong
Hi, Amani, sorry to reply you late.
As a beginner, you can manually change the material of that layer, similar to when you set the geometry material at the beginning.
You can also read some guidelines in KB: Lumerical Knowledge Base
lots examples: Lumerical Application Gallery
videos: Photonics Building (you need to subscribe it). Currently the edu videos are still available https://support.lumerical.com/hc/en-us/sections/360007813194-FDTD100-List-of-videos in LUmerical website.
Hope those links are helpful for you.
