I simulated the extinction of particle-frame nanostructures. However, the data show too sharpness SPR peak shape. How to get the smooth SPR peak? What is a problem in my simulation files. I upload my simulation file.PINF-1mL-water-2-0.4-3-longitudinal.fsp (486.3 KB)
It looks like the peaks are sharp since the resolution of the plot over frequency is low. I would recommend increasing the number of frequency points from the global monitor properties. The following post shows where to find the global monitor properties:
I noticed that you could also reduce simulation time and memory requirements by using symmetry in the x and z directions since it looks like your structure is symmetric. The following link shows how to choose the symmetry boundaries:
Hopefully this helps!
