Reply To: Unphysical Plasmonic Results – FDTD Silver spheres and rods

[Al Feg]

 

Hello Dr. Sun, I hope you are doing well, I wanted to follow up on my previous quesiton. I was able to succesfully get realistic LSPR peaks by reducing the autoshutoff and increasing PML layers. However, while the material fitting is correct, I am unable to properly simulate the resonance for the rods in question. They are large enough to support higher order resonances but my spectra are missing any response above 600 and simulating in the 600-1000 domain does not solve this for both Silver and Gold (with proper fitting) as shown in the spectra below. What would you reccomend to to fix this? Thank you again for your response and assistance.
